I think it has more to do with people's misunderstanding of what money even is or why it was created. Having money or an economy in general doesn't preclude generosity. Paper money evolved from a form of I-OWE-YOU notes. An I-owe-you note is only as valuable as the trust you put in the person writing the note. Now you can't vet every single person you find and it's difficult to transfer those notes from one person to another and hand written notes are easy to forge. So most people used metal currency as it has a mutual agreed value. Now metal currency is inconvenient for the fact it's heavy, so banks would write Promissory Notes with the bank's seal on it, which has the backing and trust of the banks that issues. Personally, I don't necessarily trust banks, but I trust them more then Joe Schmo. Eventually, the State got involved to regular the banks and create their own "Promissory Notes" in the form of paper currency.

Money is very simply, regulated, tangible trust. I trust that what I will be compensated with for my goods/services and be used to acquire other goods/services from a different party. We all have the same trust in the same money.
