Is anarcho-capitalism based not on libertarian principles possible?

The concept of ancap emerged within the framework of libertarian philosophy. However, besides libertarianism, there are other philosophies of freedom, such as objectivism or classical liberalism. It seems that any intellectual tradition aimed at achieving freedom has its own version close to ancap.

Question from Dmitry

I am currently translating an interesting article that traces the anarchist roots of ancap (funny, but many consider ancaps to be fake anarchists) from Proudhon, who, in fact, was the first to declare himself an anarchist. But there are still a few days until the work is finished, so for now, I’ll reflect on how fundamental it is for an anarcho-capitalist society to have specifically libertarian principles at its foundation—self-ownership and all that other NAP stuff.

Let’s replace self-ownership with “we are all instruments of the Lord” or “we are but a third theme in the music of Ainur.” This is simply a shift in the locus of control. Well, okay, now it’s external. Will this shift hinder the construction of ancap? Not particularly. The Lord, in His mercy, gave people commandments. The elves left humans their powerful epic, filled with moral messages. Take it, use it. In songs, you read about loyalty to oaths, or a commandment requires you not to bear false witness—one way or another, you learn the idea of a contract and the obligations under it, which means we have the basis for capitalism.

Can we do without the non-aggression principle? That no one has the right to initiate violence with impunity? No, someone does. Will this hinder the construction of ancap? Well, it depends on exactly who turned out to be the lucky exception to this principle. For example, if we declare that holy fools, small children, and women with PMS can initiate violence with impunity, this will not hinder us in building an anarcho-capitalist society. But if we declare that a certain special knightly order, sworn to maintain peace and tranquility in the Galaxy, possesses the right to initiate violence with impunity—it will be harder, although even then the situation is not hopeless, but we will be critically dependent on the procedures regulating entry into and expulsion from this order.

To what extent can ancap be built on the principles of classical liberalism? Gustave de Molinari described this very clearly. He didn’t know any of the clattering libertarian technical terms like NAP and self-ownership; he simply described how a competitive market for security services would yield better results than a monopolistic one.

What about objectivism? Egoism is a virtue. Reason is a virtue. Demanding that people sacrifice themselves for you is yuck. How is this not a basis for ancap? The principles sound as unfamiliar as appealing to the Silmarillion instead of the Bible as a source of morality, but essentially, by implementing the principles of objectivism, we get the same ancap, only with intellectual property. And yes, the state will not exist, regardless of what Ayn Rand wrote on the subject, because collecting taxes by force is to demand sacrifice from taxpayers, and forcing government officials to work for free is to demand sacrifice from them. But, of course, if voluntary self-governance coordinated by volunteers at their own expense or via donations is “the state,” then okay, let it be the state, but for us libertarians, this is simply ancap.
