It's wild that merchants are still paying ~2-3% from each sale to banks & credit card companies. How come crypto has not won yet in C2B payments?

Here're the necessary components:

For consumers: token incentives, payment app, tradfi-grade account statements, on-ramp from banks, stablecoin savings with yield

For businesses: point-of-sale apps on phones/ipads, stablecoin account with yield, off-ramp to banks, (+ token incentives)

Banks & credit card companies bootstrapped this in the 60s/70s, why can't crypto companies do this today?
