The issue with your argument is that transaction fees are pretty much the most obvious example of market forces at work. If it were unsustainable for Visa to operate with its low transaction fees, then it wouldn't be in business. If it were possible for a good crypto product to offer lower transaction fees, they would do it. Literally right now we're looking at the proof. The data/experiment is already here. When you hear people talking about how wasteful crypto is, it's because the data are already in and we're on to the analysis.
