I am very sure that one day, traditional Bank will begin to accept Bitcoin as a legit medium of exchange, people need to be given freedom to deposit their BTC directly just like the regular money. I believe that this will come to pass when the major world powers officially recognizes and adopts Bitcoin, this will make a foundation for banks to stand up and integrate it into their financial system. I believe in Bitcoin .
Several questions arise:
Why do we need banks at all then?
The price of bitcoin is constantly changing, and to pay you need a partner who will sell bitcoin on the exchange and send money to the merchant's account.
Is bitcoin convenient for shopping?
I think not, if you can pay with stablecoins in optimism, arbitrum, polygon, BNB, Solana quickly and with minimal commission.
