Trust and security, maybe, but actual utility? That's far from clear. Cryptocurrencies have a rather extreme threat model and it's not clear at all that people who are not regime critics or criminals (I don't mean to disparage suppressed people here by lumping them in with criminals though) really benefit from that model.

Most people are quite happy with trust-based currencies which don't have the proof of work overhead. Cryptocurrencies have their utility, but not for the whole population.
