I doubt any seasteading community will ever give a government something to worry about. These kind of intentional communities always look attractive on paper but are very limited in practical ways. If they are small enough that they remain philosophical uniform they can't harness growth; and if they grow, they quickly diverge ideologically.
I live in the middle of the ocean - on an island of 200,000 people, and I can tell you no amount of money or intellectual curiosity would make me take my kid to an even smaller, more insular community, with fewer opportunities, no matter how sympathetic I was to their governance model.
