Elon did go straight to the heart of the US government by taking control of the Treasury system. And if he has Trump's blessing to just arbitrarily change things, he can really remake the US.

Quite unprecedented times. While there could be a ton of lawsuits I think they won't be able to catch up with the changes. That seems to be the point, move fast enough that there is no recourse.

I see that same strategy happening with the tariffs + escalation with Canada.

It's a power grab by an unelected oligarch. If this happened literally anywhere else, American media would be calling it a coup.
