I'd take this book with a grain of salt. I don't think they've consulted with an IL/maritime lawyer (or a lawyer at all?). Seasteading might sound like a hacker's dream but there are a lot of issues not explored in this book that would be incredibly important for anyone considering investing in this idea.
1. EEZ is not 200nm from the territorial sea. It's 200nm from land, they didn't read the UNCLOS definition properly "The exclusive economic zone shall not extend beyond 200 nautical miles from the baselines from which the breadth of the territorial sea is measured." (Article 57, UNCLOS).
2. The contiguous zone is not "pretty much the same" as the territorial sea.
3. They don't really seem to understand what sovereignty is or how the international legal system works... a common theme of people who've previously tried to start their own countries. It's important to understand how flags work WRT sovereignty.
