Brother I’m hearing what you’re saying. I get what you’re getting at, I’m not missing your point.
What I’m saying is gold WAS the primary trade between nations for a reason. For thousands of years. That means it was working and there was reason to use it. Not just gold, but commodities. Commodities are still used today in trade (exports and imports).
Gold isn’t used today because technology has gotten better at faking gold with lead. Banks and nations still stockpile gold for a reason though!
