This is dumb. Imagine there's a totally cashless economy that keeps out the unbanked. But then a merchant could price gouge the unbanked. But then there'd be competition for this high margin unbanked business. But then the merchants would compete for the unbanked by lowering their margins. But then equilibrium would be hitting the unbanked up for precisely the inconvenience overhead of dealing with cash. Unless unless unless someone interferes with the market in a regulatory way. Or gets impatient waiting for the inefficiency to right itself. Sheesh.
