That doesn't really look that they're really "independent from the State".
I agree with you. I think seasteading is a noble cause and a very interesting idea, but implementing it on a small scale of two people living in a single small cabin is not feasible. Their website states that they used a solar-powered purifier for their water needs, and solar power for the rest of their electricity. It also, however, states that they had a back up diesel generator. The diesel has to come from somewhere, and they are not drilling for it themselves. Their site also made no mention whatsoever of food or farming. If you want to live separate from any country or state then you need to be self-sustainable, and a huge part of that is being able to grow your own food year-round. That's simply not possible in such a small space, meaning they are still depending on a country for the bare necessities, regardless of whether they are living within its borders or not.
This has been all over the news of late.I would have to agree also that the idealistic lifestyle is a little floored.... It would be wonderful though to live free from all government jurisdictions but on their small scale certainly not feasible.You really have to admire their courage and ingenuity though. Wouldn't catch me living on that little thing.Hope the government can see some humour in it.
