"Linda and Morris Tannehill believe that big businesses will tend to pay the bulk of the defense costs (since they stand to lose the most in the event of an attack); they would then pass on the costs to their customers, and so the costs of defense would be spread out among the whole population.A landowner seeking to establish a community may sell or lease the land with provisions written into the deed or lease agreement, requiring the new owner or tenant to pay for defense on a permanent basis; this same technique has already been in some neighborhoods to ensure that residents pay for private streets shared in common by all of them.
