Security is a service, like any other, and we do not need a monopoly provider of this service. Infrastructure, even today, is mostly privately built, contracted by the governments. The "end of government" would only mean the "end of monopoly provision of security."
Begging the question. Security means that one's basic needs of food, shelter, and protection from harm are met. It is not a service. These needs can be self-provided.
I can cook a meal for myself. That does not mean that providing me with a meal is not a service. And when I speak of the "service" of security, I am specifically referring to provision of the need of protection from harm. Though Food and Shelter are certainly services that can be provided, they lie outside the scope of most private defense agencies. (And outside the scope of Government as laid out in the Constitution, as well.)
Definition of service: The action of helping or doing work for someone.
Again, you do not need anyone else to protect you from harm.
You're right, you don't. You don't need anyone to mow your lawn for you, or to cook your meals for you, or to make your clothes for you, either. Providing these things for someone, however, is a
service. (Or, arguably, a product, but we needn't split hairs.)
It just makes life easier when we cooperate and specialize our skills for efficiency.
Again, you're correct. Specialization and division of labor make doing these things more efficient. You
could grow your own food, and make your own clothes, and be 100% self-sufficient. You'd have little time for anything else, though. Which is where service providers, such as farmers, clothiers, and the like come in.
The question is, do the service providers for
Security operate under the free-market principles which have so greatly increased prosperity in other areas of life, or do they continue to operate regional monopolies and use force to extract their payment?
