Most precious metals are worth more than their industrial applications. I suppose you could say that their value is derived from trust in the stability of their market prices.
If they're worth more than their industrial applications, how can it be economical to use them for their industrial applications?
If gold-plated contacts cost more than they're worth, nobody would make any as it would have a negative ROI.
I agree that the market cap of gold is higher than it would be if industrial applications were the only source of demand. But given that gold is used for industrial applications, it must not cost more than it is worth for those applications. Hope that makes sense.
If they're the best material for the job then manufacturers will pay the inflated luxury-good prices. People selling gold are selling it at market price, regardless of what their buyers do with it. Just because something only adds X amount of value, however that's defined, doesn't mean that one will be able to buy it for at or less than X.
