We really don't understand money anyway.
People are linear, goal oriented creatures in a cyclical, circular, reciprocal, feedback generated reality, so while markets need money to circulate, people see it as signal to extract and store. Which means ever more has to be added and ever more metastatic methods of storing what has been extracted have to be devised.
Money is not a commodity to mine form the economy, but the social contact and accounting device enabling it. So to store the asset side of the ledger, a debt has to be generated. Much of which is public debt, without which the banks couldn't function. The stock market might get the attention, but the real money is in bonds.
The secret sauce of capitalism is public debt backing private wealth.
Blood is medium, fat is a store. They serve different functions.
As a medium, we own money like we own the section of road we are using, or the air and water flowing through our bodies. It's not our picture on it, we don't hold the copyrights and are not responsible for its value, like a personal check. It is a public utility and needs to be recognized as such.
When the medium enabling markets is privately controlled, we are all tenant farmers to the banks.
Capitalism is not a free market economy.
