The two facts which prove that banks print money

To understand that banks print money two things need to be shown: Firstly that money is nothing more than state credit. Secondly that bank credit is state credit.

i) Money is nothing more than state credit... Cash has value only because it is accepted by the state. We now have a fiat money which is not backed by any commodity. Since there is no commodity it is unambiguous that the value is derived from the recognition of the state. The value comes from nowhere else.

ii) Bank credit is state credit... Bank credit is guaranteed by the state which prevents bank runs. Credit which is guaranteed by the state is state credit because there is no more reliable credit than state credit.
