The problem is more nuanced. Nobody can argue fines for socially unacceptable behaviour don't work. They do. The problem is that this method of ruling only goes so far. Eventually you run into situations where a significant enough portion of the population believes something different from another. Its in these situations, fines and laws prohibiting actions (alcohol, abortion), that things start to fail and where positive reinforcement starts to win out. All this is with the caveat that I don't want to live in a non free society, if that's on the table, then yes, negative reinforcement works fine, if you don't mind attending the odd struggle session in a north Korean death camp.
