I would argue that benefits have also come from moralizing about certain practices. Consider smoking cigarettes, for instance, which has seen dramatic decreases in use over several decades in the US [1]. I suspect that the large amount of moralizing in schools, on TV and in movies, and other places had something to do with this given that it's still more common (perhaps because it's less taboo and still seen as "cool") in certain European countries [2], not to mention many other places around the world that weren't significantly different from the US some decades ago. This has public health benefits that everyone at least indirectly benefits from, without mentioning the more direct issues such as second-hand smoke or, in the case of alcohol, drunk driving or other crimes exacerbated by its use.
