I think our children will be living on floating cities, and they will look back on the 20th Century, when people lived in primitive governments founded in previous centuries, and they will be living on modular, sustainable, floating cities that we can't imagine now, that are based on the voluntary choice of citizens. I think we will have a marvellous world in the 21st Century.

Seasteads cost money, and if you want to succeed as a Seastead you have to find ways to attract people to move there. If I was a billionaire I wouldn't want to move to a seastead, but if I was a member of the bottom billion, most of whom want to leave their dysfunctional governments, I might want to move to a seastead.

A lot of Pacific island nations are sinking below sea level; they could easily transition slowly into becoming floating nations.

Seasteaders bring a Silicon Valley sensibility to the problem of governments not innovating sufficiently. Innovators are held back and stymied by existing regulations, and we want to give them 21st century regulations on start-up governments.

Oil platforms are a technology for floating permanently on the high seas, and cruise ships are a technology for self-governance on the high seas, and if you combine these two technologies, imagine cruise ships that never dock but float permanently. Imagine if they were 10 times as big. Imagine if they were modular and could move about and you could choose the neighbours you wanted to live with.

Thinking about seasteading requires us to free ourselves of these broad political categories we're stuck with on land. People can make whatever community system they want on a seastead. What emerges will totally defy the broad categories we debate about now.
