Of course the government can never run out of money if it has control of the money supply. However what MMT fails to understand is that eventually the value of the currency is questioned. All fiat currencies derive value from belief in their worth and the only thing holding them up is acceptance of them as a means of exchange If there is no faith in their value then the currency will collapse. Venezuela or Zimbabwe would be prime examples. MMT will eventually lead to a loss of confidence and then it is game over.
