No, gold is an amazing substance in its own right. There are rarer and scarcer metals, but gold is special. This conversation relies in some part on the ductility and conductivity of gold to power our computers. It doesn’t tarnish and it is very malleable. This means you can shape it into some very beautiful and durable forms with even crude hand tools. The potential value add is very large. It’s use to back currencies is largely symbolic but it was chosen for good reasons.

Gold has properties that are similar to copper (highly electrically and thermally conductive, lustrous, and malleable), with the added benefit of being corrosion resistant. Many of the industrial applications of gold and copper are similar.

Which would suggest that if gold and copper had the same supply, the demand would be similar and thus the price would be the same. It turns out that's approximately correct— the ratio of gold and copper's prices is similar to the ratio of their supply.
