Perhaps a better way to frame the argument is that Gold is useful only because society has agreed that it is a store of value.

Things like cars and bananas are useful outside of being a medium of exchange. You can use a car to get around, and you can eat a banana if you are hungry.

Dollar bills and Gold are useful as long as society agree that you can exchange them for cars and bananas. When society stops agreeing that currency is worth anything (i.e. hyperinflation), money becomes worthless and people throw it away or burn it.

Typically, printing excess currency is what causes it to lose value. Gold avoids that because you cannot just "print" it - you have to physically mine it from the earth by exerting effort.
