This is interesting but what if you're already using crypto wallets that let you send money to your bank account? Then it doesn’t really matter if banks adjust to crypto or not you can already move your money.

I read this article and it explains it well: https://plasbit.com/crypto-basic/what-crypto-wallets-allow-transfer-to-bank-account

Its a good guide if you want to see which wallets let you do that.
