Could seasteading support anarchist society in the future?

So if you haven't read about what seaateading is exactly, it's basically the idea of creating a floating city in the ocean. These cities would be sovereign territory,perfect for trying out new social structures and economies. The idea is that people could come live and work on these ocean cities without being bothered by external governments. People from all walks of life would be given the opportunity to start over, and take part in pioneering the future of humanity. These cities wouldn't be self sustaining at first, but would rely on trade( fish farming anyone?) Energy could be attained by either burning diesel, hydro electric energy, or wind energy. They would have their own banks, or bank type organizations. All of this sets up an ideal situation for creating an anarchist organization ( not government necessarily) and provide an opportunity to show the world what anarchism is all about .
