What can we not use gold standard and international currency?

Instead of playing currency games and just printing money to devalue it why can we not use the gold standard and an international based on gold and previous metals? What is the real problem and who is against it and why? It does not seem right to just print money and play with its real value when many of us are "trusting in God" for it. It seems that money is meaningless and commodities are all that count to me. What am I missing here? If we are to "In God We Trust" does that mean that the governments are saying don't trust us?|||The government and the "powers at be" are those against using real assets as money. Gold is the only answer to real economic growth and the power to the average citizen.|||Government, like anyone else, acts in its' own self-interest. If you were in government, would you want to be constrained as to what you could do with your currency? Of course not. A gold standard works against government that is constantly trying to expand its power.|||We should have 2 economies. One with the electronic currency for the "players" and one with real currency for the rest of us.
