That's an advantage of crypto over cash. In the US, and probably similar trends in many places, only about 20% of transactions are in cash. Merely being better than cash isn't much of a selling feature, especially when it's worse than cash in some ways as well: keep your crypto in an exchange and it might get hacked. Keep it offline in a local wallet(s) and it stops being useful as a medium of exchange in most places you'd use cash. I'm not saying these problems are insurmountable, but if they are then there's still a very long road ahead to get there.
