Me too, I am puzzled since bitcin is alreay a decentralized currency. I think in my opinion he wants all systems even the banks to be removed? Fully decentralized country? I think the government will not make it happen.
In other words, bitcoin is just evolving and he still wants each and every one will be using decentralized assets (hopefully bitcoin) and without any need of any centralized systems.
Hopefully we are already moving towards that. Expecting that to happen in overnight will be insane. Because we are into centralised system for centuries. So we must need time to come out of it.
