That would only be true if the sole reason for the existence of every chain in the world was to have a coin. Once you introduce differing functions then the coins become coupled with the chain's underlying function, and therefore different from each other in kind, making common-denominator value comparisons somewhat absurd, like saying t-shirts will win out over socks in the end. As long as people need socks for their feet then sock coins will be valuable in a value-context all their own.
