Digital cash needs several features to even start getting adoption:

Stable value

Fast finality, low fees, high throughput

Privacy/anonymity/fungibility

Usability

No cryptocurrencies meet these requirements so far.

They have to do all of that and do it better than physical currency. I can hand you an envelope with $10 in it and I don't have to record it in a centralized ledger that everybody can see. I'm waiting for a cryptocurrency that is decentralized to that extent.
