In the deepest sense money isn’t real. It’s true. Intrinsically it has no real value. It’s just a fancy piece of paper. If you were to take our money to an alien world what could you use it for? Money is simply a mutually agreed upon token we use to exchange for things that provide REAL VALUE to us like food, community, comfort and shelter. It is the thing we buy with money or the thing people buy from us that has actual value.
