Suppose in an alternate history, 21st century USA operated on the barter system... no system of money is used. It has all the technology of the 21st century (computers etc). Just no money. The knowledge of "what money is" and economics is there, but for whatever reason they've chosen to stick with barter.
Now the government decides to introduce money. What would be the steps to create money, get it into circulation and then get people to use money instead of barter? ie: how do we get the current american financial system from scratch.
I ask this question because I've tried to understand money creation, but I'm always a bit puzzled because it starts with a money system already in place... I want to understand how it would be created from scratch.
