There aren’t many bullion investors who haven’t thought about using their stash to buy groceries one day.
Most of them bought metal in the first place because they know something important about history. Fiat currencies eventually die at the hands of irresponsible leaders, and it can happen fast. People caught with nothing but worthless paper in their wallet will have to resort to barter.
That said, the days of gold and silver functioning as circulating currency for any extended period of time are probably behind us. It is hard to imagine people giving up on the convenience of electronic payments and doing all of their transactions in person, with a physical exchange of coins.
While the days of people routinely carrying and using physical coins are gone, gold and silver have never stopped working as a reserve asset and a superior form of savings.
Convenience isn’t the only impediment to gold and silver resuming their role as a medium of exchange.
