I figured regulation is the way most countries can push back against crypto because an outright ban is hard to implement and more likely for people to circumvent. If you make the case that your coin should be centralized through digital exchanges ran by central banks, I'd imagine new adopters to crypto would be more inclined to give up control of their private keys to a 3rd party. There's a lot of money to be made through crypto exchanges unfortunately, so central banks wanting a piece of it was expected. The solution, obviously, is to never use exchanges but new users will still find the platforms attractive.
