There's no such thing as intrinsic value. Gold has value because humans value it. Humans value it basically because it's shiny and somewhat rare, but the value is something we project onto it.
It is a fringe application, regardless of downvote. Usage in electronics is probably less than 1% of the demand for gold. That's the very definition of fringe.
Nobody thinks intrinsic value for gold means that the universe likes wearing shiny gold jewelry and that places a floor under its value.
