Yep. Probably it's an experiment they wanted to carry out to try, like a kind of holiday, for at most some months or a few years - hoping that other people could join them. However, I think there are better places to do that than military dictatorships.

And I believe even if they succeed[ed] (maybe they try it again, I don't think they really will get killed for that, even in Thailand!) that the subsequent steps, providing a "libertarian ecosystem" for essential services, is much more difficult than the first step they've started (building this "seasted house"). For example, take this Liberarian community in Chile with the name taken out of this famous Ayn Rand novel (I don't remember the exact name, something related to "John Galt" - Edit: found it, it was "Galt's Gulch"), where at the end they got into legal conflicts between themselves (not only with the State).

I however disagree with bbc.reporter - I think a Libertarian/Anarchist settlement (like a seastead) may be possible, but there is much work that has to be done for that.
