Literally a Ponzi scheme, but not the bills, the Fed.

There is no such thing as "intrinsic value", bills don't have it, nor the gold, nor the silver, nothing has such a thing. The value is subjective.

Gold is better than bills, of course, because it's scarce and banks/governments cannot print it, but it has no intrinsic value.

The only thing that backs up the bills, the gold, the silver, etc., is the human will.

Have you seen how a place can become economically prosperous simply by injecting paper? Or on the contrary how can be left desert by the shortage of such? Does paper create wealth?

No. Paper is an illusion, like gold, a representation that we use to externalize and materialize our will.

We could literally use shit, and if we gave it value nothing would change. The value is in our head, not in the object.
