Money in the US is whatever Congress regulates it to be. If Congress decides clay bricks engraved with appropriate seals is the money of the United States then that’s it. There is nothing in the constitution that demands gold and silver be money, the constitution only says Congress has the authority to coin money and regulate the value thereof. Constitutionally speaking.👍😄👍
And I do believe that Article 1, section 8 clearly spells that out:
The Congress shall have power to lay and collect taxes, duties, imposts and excises, to pay the debts and provide for the common defense and
general welfare of the United States; but all duties, imposts and excises shall be uniform throughout the United States;
I left out anything not germane to taxation.To borrow money on the credit of the United States;
To coin money, regulate the value thereof, and of foreign coin, and fix the standard of weights and measures;
To provide for the punishment of counterfeiting the securities and current coin of the United States;
All the best,
