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.

Evolution is variation and selection. If you can vary alternatives, and select among them, improvement emerges. It works in technology, in apps, and in life itself. What stunned me about seasteading is that it's a technology for variation and selection in governance itself. The reason some two hundred nation-states do a poor job of governing seven billion people is that they don't vary, and people don't select.

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.

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

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.

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.

People can leave seasteads, or people can choose them, and people can create new seasteads if they want. This fluidity will engage an evolutionary market process that'll allow a diversity of societies to emerge that will in principle be superior, simply because people chose them. Governments on land don't allow this fluid dynamic of choice.
