There's a difference between utility and value. Plastic forks, knives, and spoons have high utility (in that they help us to eat). They have very little value, and can be purchased at any dollar store. So the blockchain doesn't have intrinsic value because the crypto currency doesn't have intrinsic value. Utility, for many use cases, it does have.
