Great post! I love the idea of seasteading. One of my novels-in-progress has a seastead on an old cruise ship. I didn't know that it was being done in real life. I was just trying to think of the most likely form a near-future seastead would take, and a cruise ship seemed to be the most obvious and efficient choice.
