Decentralized systems don't provide cryptographically-assured accountability, they require cryptographically-assured accountability in order to function correctly. If you give up the decentralization requirement, and instead federate authority across well-regulated entities, then you don't need the crypto, not as a base requirement anyway. And you still need the regulation, because all this fancy cryptographical assurance does is prevent man-in-the-middle attacks that arise from the decentralization requirement, and you still need to regulate the input and output--which is where all fraud occurs anyway.
Exactly. The hard problem is to build and maintain the democratic institutions required by a developed country. I find some people seem to be willing to gamble that for a tech solution.
