I like the idea of this developing into a society based upon blockchain.
If the seastead takes off and becomes stable it could create a very rich zone for blockchain development and real world testing, becoming the blockchain equivalent of silicon valley and attracting a lot of interest and investment on the world stage.
This is a very good notion. I like that. It can be a good breakthrough in human history and would become the 5th "industrial" revolution.
Countless things can be done through blockchain and irs a good place to start something on a notable scale
