I've have read swaths of it. I saw nothing 'sovereign' about what's now better called 'the network state'. I see it along the lines of The Zeitgeist who were openly pushing post-state blockchain based Communism.

- There's nothing 'sovereign' about being unable to buy or sell bananas without a electricity and an Internet connection.
