I don't want to legislate lower rates, I want to remove the regulatory barriers to entry for competition. And yes, credit cards do more than just move money around. This is part of the problem. Sometimes I want to just move money around, but in the U.S. it is actually impossible to do it in a way that is 1) fast, 2) cheap and 3) secure. There is no technological limitation to this. It's purely a result of regulatory capture by the banking and traditional money-transfer industry (e.g. Western Union) serving as a very effective barrier to entry for any competition.
