A major portion of the cost of defense against foreign aggression in a laissez-faire society would be borne originally by business and industry, as owners of industrial plants obviously have a much greater investment to defend than do owners of little houses in suburbia. If there were any real threat of aggression by a foreign power, businessmen would all be strongly motivated to buy insurance against that aggression, for the same reason that they buy fire insurance, even though they could save money in the short run by not doing so. An interesting result of this fact is that the cost of defense would ultimately tend to be spread among the whole population, since defense costs, along with overhead and other such costs, would have to be included in the prices paid for goods by consumers. So, the concern that “free riders” might get along without paying for their own defense by parasitically depending on the defenses paid for by their neighbors is groundless. It is based on a misconception of how the free-market system would operate. The role of business and industry as major consumers of foreign-aggression insurance would operate to unify the free area in the face of any aggression. An auto plant in Michigan, for example, might well have a vital source of raw materials in Montana, a parts plant in Ontario, a branch plant in California, warehouses in Texas, and outlets all over North America. Every one of these facilities is important to some degree to the management of that Michigan factory, so it will want to have them defended, each to the extent of its importance. Add to this the concern of the owners and managers of these facilities for their own businesses and for all the other businesses on which they, in turn, depend, and a vast, multiple network of interlocking defense systems emerges. The involvement of the insurance companies, with their diversified financial holdings and their far-flung markets would immeasurably strengthen this defensive network. Such a multiple network of interlocking defense systems is a far cry from the common but erroneous picture of small cities, businesses, and individuals, unprotected by a government, falling one by one before an advancing enemy horde.
