The problem(s): There are only two real uses for gold in the world, i.e. jewelry and electrical connectors, and the amount of the stuff stashed at Ft. Knox has to be billions of times what the human race will ever need for jewelry and electrical connectors.
Moreover there is no shortage of the stuff outside of Ft. Knox. Every ounce of the stuff which has ever been mined since Adam and Eve and Alley Oop is still around, minus wear and tear.
In theory there actually is a third use for gold, i.e. it would be the most perfect metal possible for waterfowl shot, half again denser than lead, soft, and totally inert; don't hold your breath waiting to read about anybody doing that with it.
In other words, the value of gold is 100% related to psychology and psychiatry, and zero percent related to physics or economics. That's always kept me from wanting to own the stuff.
Well, that would be about $5,000 per round or more!
I prefer depleted uranium; much cheaper. And it's well, sorta inert...
