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.

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.

Seasteads are a technology for anybody to form an alternative community based on their unique values - for communities to organize themselves however they want. Seasteads are their chance to demonstrate their vision can work. All that matters is that people can create, join, and leave seasteads voluntarily. As long as people can choose among seasteads, the best ways of living together will prosper, and the ones that people don't like will fail.

If seasteads advance blue-energy technologies, they'll create blue jobs. Millions of poor people living under exploitive governments are looking for a better choice. Seasteads won't attract them without offering them better options.

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.

Once you provide people with a platform to start their own country, every conceivable type of innovator reaches out to you with their own idea.

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.
