Libertarianism and anarcho-capitalism is just pretty much interchangeable, for the reason below.

The keyword here is 'leads'. The libertarian's lack of government leads to a criminal enterprise, ie. a dog eat dog society.

As for small police force, what if police is outsourced to businesses? E.g. PIs, using AI.

If you still have military (and in this case, you do), you can just declare martial law, and use your military.
