Thanks EZ. One thing I've noticed in everyones explanation is that although gold goes up, becasue of the dollar going down, the gold isn't worth the 20,000 when you decide to sell and use it for something, it is only worth 10,000, because, as in your scenario, the dollar is only worth half of what it was when I bought the gold. But I see that the gold is still worth twice what my dollars would have been worth if I had kept them.
Thanks all for helping me understand this better.
