Ok, sure.

Justice needs to be standardized and consistent. You cannot have a bunch of separate organizations with different rules and systems applying the law. It is perhaps the biggest example of where the government is needed because of a huge amount of consistency required.

The Police Force is the same. Plus, it is not exactly a service that you want people to have to buy, considering that they need to solve murders where people will not know who died, as well as breaking up gangs and drug rings where there may not be a lot of complaintants.

Roads require central planning. The government is central planning. Yeah, central planning is better when central planning is required. It would be near impossible to build interstate highways through the private sector considering the size, scope, and magnitude of such a project, and the amount of support required.

My examples are very clear cases where government will do a much better job than the private sector based on the idea that a single, combined effort is required to build them.
