>Money has no value of its own. It's no commodity. It's a counter for the value of stuff and services agreed upon by its users.
Money is a token for human work energy and our finite time alive, as well. Life energy is traded for metal, paper, or 1's and 0's, in theory to exchange with energy expended by another person somewhere, but in practice, it gets hoarded to obscene degrees, then we need to print more. Usury is the sin of all sins, because it takes precious human life energy for nothing. Muslims are right about that.
