Oh come on Purple Rabbit, an intelligent person such as you should know better. Nobody here is supporting (or even mentioned) privatizing police forces, or anything related to your strawman example.
As MeatBall (I think) already said, governments should make the rules, but they shouldn't tell people how to live their own lives. It's a balance between personal freedom, and when someone's personal freedom affects that of another.
An example would be in the legalisation of all drugs. It should be a right to do whatever you want to your body, but if someone thinks they can get high and start driving a car, they are going against the law. Personal freedoms are good when you are at home, or with friends in a safe environment. They are not, however, above the law.
