I do understand the implications of what you are saying, Little Hawk, but to my mind utilizing gold or other metal as the measurement of wealth is a human construct. There was allegedly a time when beads were the standard among Native Americans. In another region and a different era, a pile of furs was the symbol of prosperity (I know. I know- because the furs implied the ability to turn them into real wealth, meaning gold). In future, wealth may be measured by access to water.   My point is that the human construct was and is dependent upon circumstance and culture.

Little Hawk: "By the way, since all national currencies in the world are now unbacked fiat money...everyone is vulnerable this time. Not just one nation this time. Everyone."

Granted. At the same time, does that not imply the possibility of a new wealth measurement?

I just thought of 'scrip', an IOU, a piece of paper that acknowledges the debt of the payer to the payee, a system that is vulnerable to abuse in the wrong hands but that has worked for centuries.
