Doherty argues, in effect, that Friedman's effort to simply go out and float a boat on which one can do whatever floats one's boat is parasitic on earlier “folk activist” aimed at persuasion. It is hard to find 20,000 people who will commit to moving to New Hampshire for the cause of liberty and, as Brian points out, it's even harder to find people who will now commit to moving to a man-made island. The viability of projects like Seasteading seems to depend on the success of prior evangelism.
That said, one of the merits of Friedman's “dynamic geography” is that it is not really a “libertarian” project at all. As he writes in his Unbound lead essay:
Because we have no a priori knowledge of the best form of government, the search for good societies requires experimentation as well as theory — trying many new institutions to see how they work in practice.
I think there's good reason to expect competing sea-top jurisdictions to settle on a scheme of governance more libertarian than what the world's current nation states have to offer. But I also think there's little reason to expect a seastead to embody the system of most libertarians' dreams unless a lot of libertarians coordinate and settle there. In that case, it's really clear that creating a libertarian society from whole cloth depends on the prior existence of libertarians, which depends on the success of the folk activism that produces them.
