OK, so... if a special exceptional group of people don't have the magical superpower to pass laws to ban, e.g. murder, assault, and fraud, who would you propose do it? I might point out that private police services and private fire services have both been tried in the past. They are universally disastrous because of conflicts of interest that are obvious to anyone who thinks about the problem for five minutes.
(I also happen to like the whole 'democratic accountability' idea, also not present in private organizations, and also the extra services my government provides me which are not related to keeping warlords from taking over. Those services saved my life repeatedly, after all.)
