Prisons for one.

You seem to misunderstand the role of governments though. Citizens and taxpayers are not shareholders seeking to maximize return on investment. The government exists to provide for national defense, rule of law, postal service, and domestic security. Private industry would have an incentive to not provide these services for free riders (the poor, those who dodge payment, etc.)

Private industry also ignores externalities in their pricing, which is why we have regulation. I quite like not having to pay for relatively clean air.
