Economists and advanced nations won't like that...too simple and fair, they will lose their edge LOL
I still believe that it is not possible/sustainable after a certain economic threshold is reached. Gold will be way to expensive since we are now talking in trillions of dollars (in US debt alone).
Imagine adding all the value of all the properties, commodities, etc. in the world then dividing that by the amount of gold available...how much is an ounce going to be? Frankly, I have no idea but I would hazard to guess it will be in millions of US dollars. How rich do you think will this make a nation who have gold mines? Is it equitable? I personally do not think so. But I am a nobody so do not listen to me.
