Speaking of governance, any closed loop system is a permissioned ledger/centralized company/or kind of shareholder directed business and not an actual decentralized currency. You're usually required to go through specific channels in order to go public and issue shares of a company, so these things might end in legal mayhem. The legal and regulatory system doesn't know how any of this stuff works, but once they figure it out, the shit is gonna hit the fan for PoS coins.
Something like Peercoin and Blackcoin (not a fan but whatever) might go unscathed because I believe the entire supply was mined and not issued via IPO. It's not really a problem for Eth because the load capacity of the network will always be abysmal because it can't be partitioned, functioning only as a commercially unviable proof of concept. The market cap for Eth should crash to nothingness long before the legal framework catches up. Maybe that's why Vitalik is hiding in Switzerland right now, just in case the SEC figures things out sooner and wants to make an example.
Have you omitted Nxt on purpose because it is not a permissioned ledger/centralized PoS system?
If it wasn't intentional and you simply forgot it exists, can you summarize how the shit is gonna hit the fan for Nxt once the regulatory system figures out what they're supposed to figure out.
