Humanity has a gigantic demand for the ability to carry money around with them and in a broader sense conduct trade with very little friction. This demand is what gives intrinsic value to many precious metals, because they are difficult to counterfeit and the value is actually stored locally instead of needing to trust a third party.

Likewise, blockchain technology also has intrinsic value because it accomplishes the same goals even faster, cheaper and more reliably than precious metals. The technology itself is valuable, but the individual currencies are only valuable because of winning competition for customers.

I agree that gold is liked too much. There are astroids in orbit that contain more gold than all the gold mined and mining scouts are already being built. "No intrinsic value" should not be a negative concept in the first place. It can mean it has no "natural" value, or that its value relies on some other thing being true. Either its bad because its 'unnatural', or it is bad because if someone were stranded alone on an island with it they would not have a use for it.
