Nonsense. For 5000 years there has never been a period you could not use gold as a store of wealth and a medium of exchange no matter what the turmoil or circumstances.
No argument on that point. It is a store of wealth.
And maybe I’m wrong, but for example, if my neighbor has 20 gallons of gas that I need, is he more likely to take a thousand dollars cash, or a quarter-sized piece of what I say is gold? Certainly, a bag of silver dimes may be traded and everyone knows they’re real, but if people are iffy on cash, they’ll be iffy on about anything else too. Except maybe a dressed out deer.
