[ForGod'sSake]

A common national currency is the design of the founders.

Thanks. Something else the Founders probably got right so I don't understand the author's problem with a national currency unless he wants to go back to the Articles of the Confederation. From most accounts, they were not a good system.

Well a libertarian purist is going to say we have no need for a federal government (and by extension it's currency) at all. In theory it's true enough but that is not our system. It is not a purely libertarian system and I dare say it even carries some elements of socialism.

A good test of a federal power, without even looking at the words of the Constitution, would be "does it strengthen the states in general, facilitate the trade between them, or enhance their position on the world stage?" If it does any of those things it is probably constitutional. If it doesn't, or if it harms states or people in some way, it is outside the purpose of the federal government and it probably isn't constitutional.

Our US Senators are supposed to be the keeper-guardians of that relationship between the states and the fedgov, but the seventeenth amendment has changed that in effect.
