No, because "crypto" is only a subset of "blockchain."
Blockchain can be used for a lot more than just digital cash. It can be used for storing immutable logs of any data/content. That implies endless use-cases.
Yes, transactions can be viewed as contracts, but the mediation is already accounted for by that specific blockchain's consensus algorithm & proposal/dispute resolution system. Most of the good smart contract blockchains already have systems in place for all this.
