Seasteading- Cool? or Crazy?

I read an article in Wired magazine recently about Seasteading. Where people want to go out and make a floating island and call it their own country, and establinsh an independant government. Many liberals are into it. I don’t think the U.S. would allow such a thing though. I mean don’t we own all the waters and international water lines already. Like places where boats from other countries cannot go unless they are allied and such. I dunno, just though it was interesting.
