The real problem with money is that some people confuse it with wealth. Money is not wealth. It represents wealth. The attitude seems to be that if people, or the economy, don't have enough money, why not just print some. It is just this kind of thinking that usually brings about the final collapse of every Price System.
Money is a commodity, like bananas or toothbrushes.
Only it is a commodity that isn't real, so the supply of it can be controlled easily by governments. To make food, you first have to grow it, then harvest it, and, finally, transport it to where it is needed. The same goes for any other commodity. But you can make money as fast as a printing press can run. The only thing physical that you need is paper and ink.
