Try taking a gold bar down to the gas station and buying a tank of gas and a hot dog. Do you have change for this? A couple of doubloons and a nugget? It's battering. Gold is a commodity. So if things really did get that bad, gasoline, food, water or anything else (batteries), would be a much better bargaining medium. That's what people don't understand when they make this argument. If you hold the physical gold, the value is up to debate and barter, your $1000 worth of gold just became $50? If you hold certificates, then it's just worthless paper. So the scenario where gold works best is short of total collapse and in which you can get it converted to some foreign currency that is still accepted in you home country. Again, in New Orleans, people didn't suddenly break out doubloons and start normal operations, so the short term is out. Where is gold a reasonable investment for the "doomsday" scenario? I'd really like to know, because logically I can't think of a good reason to hold gold.
