Try to think outside the box, ok? The private sector does everything better than government and everything which the government does has been performed by the private sector.
The only purpose of government is to defend you from other governments. It's a protection racket. And it doesn't even do that well.
A person is found on the sidewalk dead of foul play. No ID (wallet obviously stolen), no witnesses. Assuming the nation is governed by anarchy, how will he be identified and how will his killer be brought to justice?
