If they want to protect themselves from runaway inflation they need to back their paper with something. Using oil, copper or whatever would work but unfortunately those commodities have a use and inflating their price would cause real hurt in the economy. However, using gold is simply coming to the understanding that gold is the only real currency in the world. If the people lose faith in paper (which looking at the queues at the mint's around the world, they have) then gold will be used... if not dictated to them, people take this up themselves e.g. recently in Vietnam and now spreading around the world.

Inflation will force their hand.
