Yeah, there are definitely times when private regulation works beautifully but if I'm going to choose between getting poisoned and seeking redress and government banning use of the toxin preemptively, I probably look to government. I'm not sure there is a simply applied concept for teasing out individual cases where private is more useful. We have to case by case this which we do when Presidents stop enforcement of regulations and people do or do not get pissed. Humans are involved so it's complicated.
