Werner’s second claim is patently false, because the ”evidence” he presents in his paper only describes banks’ ability to create money out of thin air — he presents no evidence for non-bank entities’ inability to create money out of thin air. Thus, he presents no evidence that banks possess an ability non-banks do not possess. And yet, he claims to have done the opposite."
This is awful semantic gaming to "prove" that a false claim was made. If the definition of "money" is fuzzy and there are different kinds of money, if "bank IOUs" and "private IOUs" are materially and legally different from one another, then the strongest interpretation of Werner's words must be taken: He is talking about the sets of money that do not include IOUs from random private entities.
Clearly, banks are special in this regard and the amount of bank-created money on the money supply is enormous, whereas the impact of private IOUs is so minor that we can disregard it.
