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.

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

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.

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.

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.

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.

The first seastead happened fifteen centuries ago. The result was the most beautiful city in the world, Venice. People who were sick of their violent governments fled to the water, where they built civilization on stilts. That startup society - a free city-state on the water - became so successful it dominated the Mediterranean for a thousand years.
