I saw the movie Waterworld and I dont think I want to live that way. I've become quite fond of trees, mountains, open spaces, and long hikes without a lot of people around.
Anarchy sounds pretty silly to me. Friedman already says they will need police to make sure they aren't harboring terrorists. Sounds like laws and government to me. Building codes? I would think you would need those on a floating community. Maybe a fire department too. Probably like a community maintenance fee. Sounds like a tax to me. What do do with those citizens who cant care for them selves, the sick, the mentally ill, the young, the unskilled? Row them to the mainland ald let some government care for them?
