Then why did sir Allan write an article saying that one of the roles of a fiat currency is to create money to finance the deficit? Was he wrong?
Right, the tract linked in your post 94. Pretty heady stuff: "Deficit spending is simply a scheme for the confiscation of wealth. Gold stands in the way of this insidious process." He may have changed his mind since then, because in the forty years since he wrote that (if he wrote it) we've deficit spent, stayed off gold, and real private wealth has quadrupled.
Regardless, the article didn't specifically say the Fed prints creates money to finance the deficit. Congress is in charge of deficits, and the Fed's job is supposed to be holding inflation down around 2 or 3%.
