> this will never work because governments will never allow for disintermediation of their currency because it’s one of, if not THE, primary sources of control over a population

Isn't this similar to saying "democracy will never work because kings will never allow it"?

I'm not saying it's exactly the same, just the fact that some existing power structures do not like the change does not guarantee they will manage to stop it. Sometimes they do, sometimes they don't.
