anonymous question

In the previous post, the question was phrased ambiguously, and it seems the author has clarified it, so now the answer will be slightly about something else.

It’s quite funny, but as far as nuclear bombs are concerned, all libertarian principles are working right now.

In the realm of relations between states, there is de facto anarchy; law is decentralized, governed by the willingness to bear the costs of certain actions, the institution of reputation, and other concepts dear to the ancap heart. When libertarianism is fully implemented in human society, the mechanisms will remain exactly the same, only instead of states, there will be other legal entities, without a territorial monopoly on aggressive violence. They will be equally able to negotiate among themselves on the transfer of technologies and materials, on mutual control measures, on measures to limit access to the nuclear club, on sanctions for violating the non-proliferation regime, on the ban on detonating bombs wherever they please—and similar things we are well acquainted with from media headlines.
If even such ferocious thugs (from the perspective of their relationship with the law) as states manage not to detonate bombs in populated areas because they are constantly staring each other down, then under libertarianism, on average far more sane legal entities will be able to reach effective agreements among themselves.

Again, a nuclear bomb is an effective means of inflicting damage on a large territory, and under ancap, large territorial jurisdictions are extremely unlikely; most likely, they will be contractual, or even arise situationally for each specific legal conflict.

That is, the point of the combat use of nuclear weapons will be near zero; only the scientific and entertainment value will remain. Yes, those very recreational nukes. In deep space—why not.
