Someone suggested me that gold doesn't rust and that stability was interesting as a long time token. But I don't find any usage beside the social status gem.
Anyway the point wasn't the merits of gold over currencies, just pointing out the fact that it has a real status as a useful commodity, in a way that purpose-built currency doesn't. That means, among other things, that demand for jwelery in India for example, or changes in electronics manufacturing processes are bound to affect its price.
That makes it quite different from other currencies.
Some people do trade knowledge of energy sources for stuff, using money as an intermediate store of value, but most people cannot, and it wouldn't be desirable either otherwise we wouldn't have a varied and healthy economy.
