"intrinsic" seems to imply an innate persistence despite not being able to justify such innateness, just empirical persistence. It just implies things that are arguably not justifiable needlessly. gold has been persistently valuable. The universe doesn't give it an innate value.
Seeing as how cultures that considered gold a highly valued item developed independently in Europe and uncontacted pre-Columbian America, and the preference remains global today, there's clearly something durable about this concept.
you could say that the reasons for valuing gold probably aren't going to go away anytime soon as far as anyone can guess. though even then, the market value of gold has fluctuated by a factor of like 10 in recent history as the durable abstract reasons for wanting it have not apparently changed as much. did anything intrinsic about gold change from 1980-1981, when the price crashed 82%?
That's as tangible as anything else. Nobody would say that there's no demand for musical instruments, or baseballs, because they are optional parts of life that aren't food or shelter.
Gold has intrinsic value in part because people seem to intrinsically like it for what it actually is, not just it's utility in exchange. That's fundamentally different.
