Congress has the authority (as opposed to the “right”) to “define currency” so to speak. They also have a responsibility not to run the Federal train right off of the tracks, like they have done, or rather, like we have allowed them to do.
It seems to me that any “law” passed by the Congress that directly flaunts the Constitution, is immediately null and void, and the Supreme Court has ruled as much in the past. Something tells me that ruling has been long ignored or overturned in some way that is decidedly not in our favor...
Since Federalism has failed us, it is time to get back to “These United States”...
