I wish I could give you a +ve vote (none available to me at the moment). I've had this kind of runaround on Slashdot too (see here and here). The education level of the Slashdot crowd must be higher than average. If so, the quality of fiscal and economic education in the schools must be correspondingly abysmal.
Just as a side note: at the time of my Slashdot discussion (see links), gold was around $1350/Toz. It is now, 13 months later, around $1700/Toz. The gold isn't that much more "valuable". The $US is that much less valuable (along with other currencies).
