Are there tasks that can be done more efficiently by government than by private enterprise?

There is an idea in contemporary culture that businesses are simply better at most tasks than government because they are motivated by profit and literally can't afford to lose money. Are there nay tasks, though, that can ONLY be performed by a government, or that can be more efficiently done by a government?

One typical example would be natural monopolies. It just doesn't make much sense if companies all had to build their own electricity network for example.

Another typical example are public goods. Public goods are defined by being non-rivalous and non-excludable, and because of that often suffer from the free-rider problem. If you just make people pay for them via taxes, that's often a simple way to avoid that.
