As I see it, there are the three main types of service that the city offers in any SimCity game. There's the police force, the firefighting force, and the health services. Suggesting that because a private firm is more efficient than the government, said private firm should perform firefighting or policing is ludicrous. After all, if you didn't pay your crime insurance, would they let you be robbed - even if you were in plain sight of these private cops? What about fire insurance? If you didn't pay your fire insurance, would they let your house burn, but put out any flames that jump to your neighbours' house (that is, assuming they paid their insurance)? This whole 'libertarian' thing is perhaps not the best thought-out idea.
