Here's one problem with the U.S. approach and it's not just crypto:
Crypto in the Kill Zone

It's about Regulatory Capture.
I personally think it's important to aim for a peaceful co-existence between the decentralized cryptocurrency and fiat systems, but agree it won't be easy getting there.
there cannot be a peaceful coexistance between cryptocurrencies and mission regulated central banks, only if the greed of both parties is beeing fullfilled by the working population that will be burned in the process.
even cryptocurrencies among themselves are not capable of peaceful coexistance. its a nonstop Information war.
