Murray Rothbard, in a 1963 essay titled “War, Peace, and the State“:
A final word about conscription: of all the ways in which war aggrandizes the State, this is perhaps the most flagrant and most despotic. But the most striking fact about conscription is the absurdity of the arguments put forward on its behalf. A man must be conscripted to defend his (or someone else’s?) liberty against an evil State beyond the borders. Defend his liberty? How? By being coerced into an army whose very raison d’être is the expunging of liberty, the trampling on all the liberties of the person, the calculated and brutal dehumanization of the soldier and his transformation into an efficient engine of murder at the whim of his ‘commanding officer’? Can any conceivable foreign State do anything worse to him than what ‘his’ army is now doing for his alleged benefit? Who is there, O Lord, to defend him against his ‘defenders‘?
And I won’t reproduce the footnote.
