Well, the very first assertion "Banks make currency" is not accurate in the US (the context of the article). Currency is "made" by a combination of the US Treasury and policy set by the federal reserve. The fed is a bank of sorts, but in no sense is a bank like JPMC creating currency.

The part about not backing deposits with silver and gold being fraud is pretty wrong.

Even in Ye Olden Daze, banks would send deposits of things like gold and silver right back out the door as loans.
