Gold is old because it took us a long time to work out that there was a better way of running a currency. But now that we have, there is no reason to turn back the clock on our technology. Gas lamps are old but electric lights are better. Smoked meat is old but refrigeration is just better. Same thing.
Gold is heavy, making it impractical to use on large scale transactions, and prone to shortages - your economy stagnates whenever you just can't get enough of it. And the final straw was that after World War 2, when everyone's gold ended up in the USA because they got their war supply from us, it was found that everyone could forever f**k with our economy just by withdrawing their gold deposits from our reserves - which is why we finally scrapped the Gold Standard to begin with.
And on a day-to-day layman's scale, these effects are not easy to notice, but when you are a captain of the economy or of an international large business operation, it becomes obvious that the Gold Standard is a backward technology that we are better off without.
And that is why your Q buddies are Wrong with a capital W to predict that the Gold Standard is returning. It is never coming back. Nobody in any position of economic expertise wants it. The only people who want the Gold Standard back are people who do not know what they are talking about. It will not come back. Just the mere act of buying back enough gold to do that in itself would be enough to bankrupt the US and would finish us off as a global power. We're not doing that. Q is wrong. It is an incorrect prediction.
