Not necessarily. Right now cash is anonymous. It changes hands without any record. It has no provenance. And is a centralized currency. There was a joke at the top of the crypto reddit a few days ago about how cash is just more convenient than bitcoin for ordering a pizza. It doesn't have to be government but I would like to see a trusted owner actually own the governance of a crypto currency. Right now it is way too wild west to instill a lot of confidence. Which is great way to make a lot of money quickly. But over the long term I can see a lot of issues coming up.

A non-crypto solution wouldn't have to have all of these features. These are just some of the possible desirable ones.
