Security Engineering

Everywhere, men resign themselves to the most extreme sacrifices rather than do without government and hence security, without realizing that in so doing, they misjudge their alternatives.Suppose that a man found his person and his means of survival incessantly menaced; wouldn't his first and constant preoccupation be to protect himself from the dangers that surround him?  This preoccupation, these efforts, this labor, would necessarily absorb the greater portion of his time, as well as the most energetic and active faculties of his intelligence.  In consequence, he could only devote insufficient and uncertain efforts, and his divided attention, to the satisfaction of his other needs.
Even though this man might be asked to surrender a very considerable portion of his time and of his labor to someone who takes it upon himself to guarantee the peaceful possession of his person and his goods, wouldn't it be to his advantage to conclude this bargain?
Still, it would obviously be no less in his self-interest to procure his security at the lowest price possible.

No nation can make itself secure by seeking supremacy over all others. We all share responsibility for each other’s security, and only by working to make each other secure can we hope to achieve lasting security for ourselves.

But why should there be an exception relative to security?  What special reason is there that the production of security cannot be relegated to free competition?  Why should it be subjected to a different principle and organized according to a different system?
