There was, in short, a demand for money that operated independently of the demand for a tax medium. Biddle's operations were accepted in Europe because he was seen as a Man of Much Cotton. But the money as such was private bank money, not money redeemable for a fixed value in cotton. This kind of historical situation could not exist in a Moslerian universe. In fact, that is why he must continually assert that the government control of money is monopolistic and absolute.
Any economist knows that no monopoly, even a government one, is absolute.
So sure, governments can get us under the right conditions to pay them with designated pieces of paper. But what make money system so interesting is precisley the extent to which it depends on voluntary compliance. As two seconds' worth of time shows, where the money system gets seriously out of whack people ignore the coercive power of their government and their is nothing the government can do about it. U.S. dollars are freely substituted for currency in Brazil, or Russia. Of course not.
