I kinda agree that this protocol is the perfect tool to do away with national currencies. 
The question is how do they get rid of the protocol? Banning cryptos won't work.
And ETF was not approved, surely they would have approved it if they wanted the world to switch to crypto no?
Maybe they just want people to have an alternative so that they don't oppose a cashless society but the same question remain, how do they get rid of these cryptos and force their one world currency on everyone?  Unless there is a security flaw only known to them I really don't know how they will prevent people from using them.
