The problem is that once a cryptocurrency starts to demonstrate such a market, there is nothing stopping Visa from rolling out a microtransaction fee structure and undercutting the cryptocurrency.
well great, but visa has a lot of liabilities too. Being centralized, they become e.g. liable for illegal transactions, where cryptos dont have that. This has costs, which should normally never allow visa to be competitive.
also, tbh , visa launching a microtransaction framework as easy to use as cryptos would be great news
