That’s making an assumption that precious metals will maintain their traditional roles against devaluation. I don’t know how well that would work if the problem is world-wide, or if it does, why other commodities like grains and petroleum won’t be just as much protection, if not more.
Personally I like the idea of precious metals, (in moderation), as a hedge against fiat money and SHTF scenarios. But I would like to point out that Precious metals can be confiscated by the various Governments and Powers That Be. It’s happened in the past and in can happen in the future especially if the Governments declare that precious metals are “not currency” and will be confiscated upon detection when attempted to be used as currency.
Governments and the Bureaucrats that operate them can and will become tyrants when their power is being taken away from them. And a currency crisis will surely do that.
