This is a very interesting take, but then gold is not exactly money. I mean you just cannot pay for things in gold as easily. For example, you can't walk into a shop, pick something up, and offer to pay in gold. With bitcoin, you can still do it in places that accept it.
Also the same goes with bitcoin actually, the only difference is the market adoption and appropriateness of the applications that we have. In gold, there are not much transactions because people chose gold to be invested for a long period of time. While in bitcoin, people chose it to be come like a currency that you could spend right away and at the same time, like gold, that you could invest for your future living.
