Your making a comparative contradiction with Crypto vs. Gold by saying:
"A token represents a futures value for something that has utility"
Most tokens dont have uses yet are valued very highly...
Gold on the other hand is being used in electronics and many space purposes... minscule? Maybe, but in increasing amounts.
Smart technology needs pure gold. The smarter our tech, the more gold is needed.
What happens if some high tech device is created that takes lots of gold to work?
Its hard to beat the signal conductivity of pure gold....
I will bet bitcoin that some technology yet to be developed will require gold in quantities to substantiate its value... say in 20years.
Nanotech is very promising, id put my gold and silver and platinum bet on that
