Would you mind expanding on your point? I understand that there is limited trade in gold, but why does the fact that they are running up against a limit in buying gold matter to the argument?
There's a common belief among conspiracists/Zerohedge believers that the amount of physical gold is basically fraudulent, and that the gold that is being traded doesn't exist. So when the coming financial crisis happens and gold becomes the currency of trade, when people actually open up their coffers, they'll see that it either doesn't exist or it's gold bars filled with tungsten.
