I didn't say I explained it, just that I gave it in my initial reply.

I gave examples of prevention.

As for punishment, putting the guy in a cage doesn't get the money back if he's already spent it.

There are disincentives for antisocial behavior that don't involve government. Some don't include force at all. Do you think that the only reason people act morally is fear of government? Most people do good because they're good people.

One major disincentive is reputation. The guy that steals from the old lady will find it difficult to do again if it spoils his reputation.

Anyway if you're actually interested in alternatives to government there are plenty of resources freely available online. You could also look into buildung alternatives yourself. But if you want to convince me that government is some necessary evil then your wasting your time.
