This is a very important point since one criticism of my last post is the view that “only taxes levied by the state and the need to pay those taxes in the state-issued fiat money drive the demand for, and value of, that fiat money and its use as a general medium of exchange in modern nations” is not actually held by L. Randall Wray, the most prominent academic advocate of MMT. So it turns out that, on this issue, I have to eat some humble pie!
