is this a utilitarian argument or what?
its already been proven that the most efficient and beneficial method of social interaction is through trade - this does NOT, however, over-rule the fundamental 'might makes right' in nature... we humans have just found a better way amongst ourselves...
try to open trade negotiations with that 10 mile asteriod speeding towards earth or a hurricane or tornado or a nasty pack of wolves (lions, tigers, or bears...)
ok, lets get back to the island thing - I love islands! does it have palm trees and big, pretty flowers?
day-dreaming,
