"Finally, the concluding essay is a cry from the heart on the basic reason why a person should be a Libertarian: not as an intellectual parlor game, not from the utilitarian weighing of costs and beneftis, and not because there will be X percent more bathtubs produced in the free society. The basic reason for one's libertarianism should be a passion for justice, for sweeping away as quickly as possible the tyranny, the thievery, the mass murder, and enslavement, which statism has, for too long, imposed upon mankind. It is only such a concern for justice that can inspire the Libertarian to try to abolish, as quickly as he can (and far from the Marxian sense), the exploitation of man by man."
