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

Americans are very mobile and move around and choose the communities they want. On the ocean people would be even more mobile and empowered to link up with people they enjoyed, and detach and move away from people they did not. Increasing choice is a way to foster fulfillment in people's lives. I choose my friends and I'd prefer to choose my neighbors too.

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.

We're going to draw a new map of the world, with French Polynesia as the centre of the Aquatic Age.

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.

That's the marvellous thing about seasteads; if a government fails, there's nothing much the people who live there can do about it. But if seasteads fail, they simply disassemble and go away.

Seasteads are man-made islands that float permanently on the ocean with any measure of a political autonomy. They would essentially be startup societies where people could form whatever kind of community they wanted.
