Can you elaborate how crypto solves this issue in an optimal way?
1. You can store cash, if you choose to. Way way way easier than Crypto. This should be the end of this argument but let's continue.
2. Can average citizen safely and reliably store crypto on their own anywhere nearly as easily and safely as cash? Otherwise, you're just at mercy of unregulated "exchanges" as opposed to "banks" and your power is even lower and the horror news stories even more plentiful.
3. Ultimately, crypto is a complicated technological stack that (and we will have a difference of opinions) government, if it sufficiently chooses to, can shut down and control. Crypto introduces a mind boggling chain of technical dependencies and gotchas and risks and dangers, which are super fun for us on HN to play with and argue about, but are a pit of snakes and spikes for most regular people (and just because somebody somewhere who's not technologically adept has used crypto successfully, that does not mean they were not exposed to massive risk; you can play Russian roulette and "win", it does not make it a good idea)
