"If a criminal spies on my credit card # as I make a purchase and uses that to go on a spending spree I can fix it with the credit card company with little cost but a few hours of time and frustration."
You just made a great case for why crypto as a backend for balance transfer that's abstracted by centralized payment options built on top of the transfer network for funding balances but directly interfaces with POS outside the crypto network will almost certainly continue to grow into a thing as crypto grows.
Get rid of bank accounts, and then firewall balances behind 3rd party abstractions powered by your crypto wallet.
By all means charge my vendors 3.25% of the transaction to firewall and insure my wallet against theft.
Give me 1-2% cash back and I'll be even more excited about the prospect.
