"If the Feds run short on cash, the Federal Reserve just prints them more. Literally (well, digitally “prints”)."

Actually most money is created without the FED doing anything.

Anytime a loan is issued (bank loan, Mastercard charge, auto loan etc.) digital money is created. Any time a government bond is issued money is created. And so on.

Any time a government bond is issued money is created.

Yes, but someone has to buy the bond.

Frequently, that "someone" is the Fed.
