I suppose she would be a capitalistic anarchist who would say that every legitimate function that is now performed by government could be performed by the private sector.
If you want protection, then you purchase it or provide for it yourself; if you want to travel on a road, then you pay a fee to the owner, etc.
What do you do now? The owner is the government. You pay a fee for a license to drive. You pay a fee for an agent of the government to inspect your car, and to register your car. You pay taxes on your gasoline to pay for the upkeep of the owner's roads.
You cannot travel on a road without paying a fee (or dozen) to the owner. In your case, the owner is the government.
Why is the government a better owner than a private party?
