Lol,  man you’re damn confused ,like what are you even saying, you talk about digital dollar and then you switch and start talking about Defi. What even makes you think that the digital dollar (if there is going to be any of that) is going to be something like the Defi (decentralized finance)?

If something that is created by the government is going to be decentralized, then it is of no need to them, since the government is always looking for things that they are going to be able to control and if it’s not going to be that, then they are not interested in it. And by the way, when and where did you see the US government talk about cryptocurrency?
