I understand it fine. At least the parts of what you said that are true anyway. Much of it is false but even if it weren't, I think you're misunderstanding my meaning.

Gold being used as a currency is ascribing to it an artificial value. It is no different than say, printing a number on a piece of paper and saying that paper is now valuable. It's a rock that we take out of the ground. If we tried as hard to dig up gold as we do digging up oil, we might eventually dig it all up in a few thousand years.

Oil has value because we use it for all kinds of crap. It's so useful we also trade it because it's valuable. This is true of every other commodity. Gold has so far outpaced its actual industrial value it's functionally just another currency, victim to the same manipulations as any other currency.
