The reason why we are not using gold backed standard is that growing economy and limited amount of gold on Earth would cause growing of price of gold into ludicrously insane prices. We are using gold in industry, i.e. for gold plating of connectors, that would have to stop. Do you have golden jewllery? Better not wear them out, having a golden ring would be likely enough to get you killed.
