It would be nice if that happens, but I think Trump is also the puppet same as Biden, and he is probably going to be busy taking over Canada, Greenland, Gulf of Mexico, Panama Canal, etc...
This all sounds like more centralization and less privacy to me, and I don't see how centralized mixers would get a pass.
However, I think there is a chance of some new type of decentralized mixing to be allowed in bitcointalk.
