Gold is something I can hold in my hand. It will NEVER be worth nothing - it has value in industrial processes and making wedding rings.
Sure, but on the other hand, how would you like to exchange your gold for an equal weight of aluminum -- which is also not worth nothing, but until the late 19th century was more valuable than gold. . Or silicon, which is also valuable in industrial processes, particularly in the manufacture of semiconductors, but only after tremendous work has been done to purify it?
The fact that some physical substance always has some utility doesn't mean all that much. The actual industrial value of gold is not nothing, but neither is it all that large. Further, it's possible that in the not too distant future we could be mining gold from asteroids and shipping millions of tons of it per year to Earth. Or we could find a cost-efficient and safe way to manufacture gold, by transmuting other metals. Or we could just become better at finding it and digging it up. In any of those scenarios, dramatically-increased supply will cause the value to fall, probably even more dramatically, since much of gold's current price is driven by the expectation that it will always be valuable and evidence that that is untrue will quickly erase the speculative drivers of gold's current high price.
About the only thing I can think of which truly has intrinsic value is energy, since it is the necessary input to all productive processes. It's hard to store in a vault, though, physical or electronic.
