Did it ever really matter?

  So called reserve currencies were never important to begin with. I would be just as glad being paid in South African Rand, European Euros, Mexican Pesos, Russian Rubles, Swiss Francs, or any national currency since all currencies can be quickly traded for commodities at market price.

 Granted, it is no gold standard. But why would anyone sit on paper currency longer than they needed to. If there is a purchase you need to make in the short term. Then keep it as paper currency. For everything else, have it stored in the form of commodities.

 Your wage eventually is unable to keep up the appreciation in price. But you are still better off than those who did not convert their cash into something with a solid foundation.
