What money is, what it represents, is value. But value is a complete opaque quality. At best we have an approximation: an 'expectation' of value. Expectation results in people paying for more for misprinted coins. Expectation is the same reason that drives people to stocks, to silver/gold, to oil. Expectation can be manipulated. If you can make others expect greater value of an item (and then they exchange such a value to you for that item) than what you are giving them: that difference is profit.

To be clear, I don't like this outlook. But I've found it to be accurate to how people behave around money. It's not a sign of a healthy society.
