It's a lot of mental gymnastics that serve as a "reductio ad absurdam" argument, proving that the fundamental organizing axiom of human societies is still "might makes right" rather than "right is derived from mutually-agreed-upon moral principles".

The last arguments of kings are still guns.

The end state of all theoretical non-aggressive libertarian societies is that they are conquered through force by some form of cartel. In my opinion, seasteading, which is predicated on mutual non-aggression for prosperity, is strictly inferior to hiring a bunch of ex-CIA and ex-GRU contractors to destabilize and take over a pre-existing dictatorial country, and then rewrite its laws from scratch. The moral high ground loses to boots on the ground, every time.

If you can't or won't preemptively attack and annex another country's territory, you're better off trying to colonize space, where nation-states can't reach you as easily, or start by building the nuclear warheads, and then build the floating cities. The veneer of civilization is thin, and one gun is no longer sufficient for one man to defend his castle.
