The value of money is a variable parameter. The dynamics of the value of money, determined by the quantity of goods, is characteristic only of real money, because the resulting excess of gold money settles in the form of an ordinary monetary commodity, whose name is gold. Symbolic money is monofunctional (unlike gold money, which is characterized by multifunctionality), it can be only money, and nothing else - it cannot turn into a commodity, as gold money easily did. Of course, it is easier to print money than to create real goods.
