I don't see where either has talked much about monetary exchange in their situations. For a long time the US dollar was the "gold standard" and could be used from Australia to Zimbabwe. What if it's worthless tomorrow?
If it’s worthless than I’d prefer to have the stuff I’d need it for stored up. Even if the country declared bankruptcy and restructured debt the dollar would still be used. Now it might lose comparable value against what it formerly was but that can also be hedged with market investments. Imo in any situation where gold would be necessary for commerce the USG would first declare it illegal as tender to protect the dollar.
