Is flying an aircraft over territory belonging to another person trespassing under ancap?

Do you need to ask them for permission before flying? Is it necessary to somehow amortize the risk of the aircraft falling on the property of people located beneath it, and how to compensate for the noise of the engines/propellers? What is your personal/Montelibero/Montenegrin position on this issue?

I like how David Friedman analyzes this and many other questions (sorry for buzzing your ears with him so much). He analyzes the topic in great detail in the book The Machinery of Freedom. I have managed to get through about a third of it so far. Much more concisely—in one of the chapters of The Machinery of Freedom. There, economic analysis of law is also used as a basis for reasoning. This often allows for a fairly clear generalization of those specific answers that I have to give from time to time.

To put it very briefly, the lower the transaction costs for proposed deals to purchase rights to actions that violate others’ interests, the more convenient it is to recognize the owners’ right to prohibit such actions. If necessary, the potential trespasser will buy the right of passage. And the higher the transaction costs, the more convenient the procedure of judicial settlement of such cases becomes through claims for damages. No one defines a specific threshold altitude at which one can fly over someone else’s property, but if the flight caused damage, it will have to be compensated in court. Flights over someone else’s territory at a sufficiently high altitude (so as to at least not crash into terrain irregularities in normal mode and not frighten people with the wild roar of engines) are clearly the second case; obtaining permission to fly from all owners over whose territory it may occur is an unrealistic task.

Specifically in Montenegro, there is state licensing for the import of drones into the country, certain weight restrictions, a ban on flying above a certain altitude, and other highly sophisticated restrictions, some of which can be bypassed, while in others it proves too expensive, and it is simpler to accept that a certain application of drones is too troublesome to engage in systematically. Naturally, we in Montelibero find the complete repeal of all these regulations desirable, because drones can at least be used to take beautiful photos, which is useful for promoting the project. But, of course, the drone owner must be prepared for the fact that if their expensive toy falls on someone else’s plot, they may well lose it. The plot owner is not responsible if a cow steps on the fallen drone, or if his underage son decides to break something off this unexpected gift. He is not even obliged to let the drone owner onto his territory—here, the right of prohibition applies, because the transaction costs for purchasing the right of passage are small.

Here we filmed our plot with a drone, but this required flying over the neighbors as well

Conflicting Jurisdictions

For example, a friend invited me to a party at his house. I brought apple juice with me. Suddenly, the police burst in, and it turns out that juice is prohibited in his contractual jurisdiction.
1) Did I start violating the NAP from the moment I took it out?
2) How does the effect of another jurisdiction apply to me if I have not entered into contracts with it?
3) What happens if I am a user of another jurisdiction that the first one does not recognize and simply engages in vigilantism?

A similar question: will self-ownership help if a person runs onto someone else’s field? Can I shoot them without a trial or investigation?

What could be called laws under ancap is the codification of successful practices. Such codes, which generalize successful practices on various topics, are in demand in a stateless society because they save effort by allowing one to avoid analyzing every case from scratch. Saving effort will mean saving money, and a cheap court, all other things being equal, will naturally win in the competitive struggle against an expensive one. But even if an expensive court provides a higher quality review of the issue, there will also be demand for a cheap one; this is a natural market segmentation by price.

Thus, by recognizing the jurisdiction of a particular company over oneself regarding a certain circle of issues, a person under ancap usually has the opportunity in advance to find out which sets of norms are used within that jurisdiction.

Furthermore, humanity has a rich experience in resolving conflicts between persons belonging to different jurisdictions. In most cases, it was a convenient practice to recognize the laws of the party on whose territory the conflict occurred. Deviations from this principle were usually stipulated separately. This could be related, for example, to the particularly important status of certain persons, or to the disputed status of the place where the conflict occurred. Thus, the concept of diplomatic immunity and international maritime law emerged.

Now let’s move directly to your questions. Let’s replace apple juice with a more understandable irritant. You brought sausage to a vegan party and began to eat it with appetite alongside the salad. Naturally, for vegans, this is a very irritating situation. And they know in advance that something like this would upset them greatly. Therefore, the party announcement usually states right away that it is a vegan party, no meat will be served, and bringing it along is prohibited. Thus, your actions violate the agreed-upon conditions of presence, and you are fully entitled to be evicted from the party.

Worse, if the announcement states that the party is vegan, no restrictions are explicitly written, you are not a vegan and do not hide it, but you were invited anyway. Respecting the hosts’ right not to serve you meat, you decide to provide for yourself—and you run into a legal conflict. Here, both the hosts, who failed to explain the rules to you, and you, who failed to understand the local defaults, are in an awkward position. Usually, such mishaps are resolved by one of the parties making concessions, but if the party hosts do not concede, you will still be evicted, because this is a place where their interpretation of disputed norms takes priority. I had a similar case during a Kupala night celebration when I started kissing a guy; it turned out he was taken, and his girl confronted me for it, which caused my bewilderment: I sincerely believed that different rules apply on Kupala night—but I yielded; the world didn’t end over that guy, basically. Similarly, our hypothetical vegans might yield to you, albeit with a sense of deep bewilderment at your tactlessness.

Now let’s move from elaborate tales to conclusions.

  1. You are not obliged to follow the norms that you did not pledge to follow.
  2. You may be forced to comply with them if it is a fundamental point for the enforcing party, but not for you.
  3. You have the right to demand compensation for such coercion, but it is not a fact that you will receive it.
  4. The more the parties are interested in future cooperation, the more likely it is that they will make mutual concessions regarding a specific current case.

In light of these theses, how can we resolve the second case, with trespassing—that is, the violation of property boundaries, even without explicit damage to that property?

  1. A person is not obliged to be aware that you are against them walking across your field. It is better to put a sign on the border saying “No Trespassing,” so that the person knows that a famous Willy No-Trespassing lives here, and he is not to be trifled with (for additional reading, I recommend the well-known text about Piglet’s grandfather, floating around the internet).
  2. You can force a person to leave the field if this is fundamental for you. And if they have read the sign and ignored it, you can carry out the enforcement using lethal force, without wasting time on additional persuasions.
  3. Compensation may be demanded from you if, for example, there was a beaten path across your field, the boundary was not marked, the sign turned out to be unreadable and hidden in the grass, and then you pop out like a jack-in-the-box with a Winchester in hand and start shooting. State your rules in the most explicit form possible.
  4. The more you are interested in future cooperation with the trespasser, the more likely it is that you will allow them on your field, even if they wandered in without permission. For example, it turned out to be a traveling salesman with a magical gift of persuasion, and now he will be your permanent supplier of tin foil hats.
