ADDENDUM

It could be persuasively argued that the best method of defending human life is by working to reverse all those tendencies in human and institutional nature which lead to aggression in the first place. In this view, the military would not simply be a fighting body of soldiers following orders, but an affiliated organization of agents capable of independent action and thought- decision-makers with the tools for social betterment, ie. skills in conflict resolution, engineering, education, etc. Of course, in a radically decentralized society, almost all members would have these kind of qualifications.
An open-source, free society would dissolve the traditionally rigid boundaries which demarcate one 'occupation' (no pun intended) from another. Everyone would bear the costs of their freedom- the responsibility for assuring the security and prosperity of every other member. In this way, there would be no distinctions between various 'classes' of profession, no external police force, no external judiciary, no external legislature, and no external military. These 'necessary activities' would be an intrinsic part of every social actor, rather than an extrinsic lever for controlling behaviour.
