I'm not sure what you mean by this. The Friedman rule does not assume there is a fixed amount of money -- the rule itself recommends in some circumstances that the central bank should increase the supply of money.
The central bank is not in control of the quantity of money. Money is created dynamically by all entities in society as and when it is needed. That's what trade credit is all about, for example.
