Never mentioned anything about 'the banks' but regardless, they are still around because everyone needs to eat and you can still pay for your groceries with your card linked to your bank account which payments provide very low transaction costs and it is still fast.

Unlike Ethereum which it has gotten worse to use over time to the point that it is useless to pay for your groceries. Perhaps there are other blockchains that are better for both for setting up DAOs and paying for your food.

Oh dear.
