" It is also contended that, in democratic governments, the act of voting makes the government and all its works and powers truly “voluntary.” Again, there are many fallacies with this popular argument. In the first place, even if the majority of the public specifically endorsed each and every particular act of the government, this would simply be majority tyranny rather than a voluntary act undergone by every person in the country. Murder is murder, theft is theft, whether undertaken by one man against another, or by a group, or even by the majority of people within a given territorial area. The fact that a majority might support or condone an act of theft does not diminish the criminal essence of the act or its grave injustice. Otherwise, we would have to say, for example, that any Jews murdered by the democratically elected Nazi government were not murdered, but only “voluntarily committed suicide”—surely, the grotesque but logical implication of the “democracy as voluntary” doctrine. Secondly, in a republic as contrasted to a direct democracy, people vote not for specific measures but for “representatives” in a package deal; the representatives then wreak their will for a fixed length of time. In no legal sense, of course, are they truly “representatives” since, in a free society, the principal hires his agent or representative individually and can fire him at will. As the great anarchist political theorist and constitutional lawyer, Lysander Spooner, wrote:
they [the elected government officials] are neither our servants, agents, attorneys, nor representatives . . . [for] we do not make ourselves responsible for their acts. If a man is my servant, agent, or attorney, I necessarily make myself responsible for all his acts done within the limits of the power I have intrusted to him. If I have intrusted him, as my agent, with either absolute power, or any power at all, over the persons or properties of other men than myself, I thereby necessarily make myself responsible to those other persons for any injuries he may do them, so long as he acts within the limits of the power I have granted him. But no individual who may be injured in his person or property, by acts of Congress, can come to the individual electors, and hold them responsible for these acts of their so-called agents or representatives. This fact proves that these pretended agents of the people, of everybody, are really the agents of nobody.
Furthermore, even on its own terms, voting can hardly establish “majority” rule, much less of voluntary endorsement of government. In the United States, for example, less than 40 percent of eligible voters bother to vote at all; of these, 21 percent may vote for one candidate and 19 percent for another. 21 percent scarcely establishes even majority rule, much less the voluntary consent of all. (In one sense, and quite apart from democracy or voting, the “majority” always supports any existing government; this will be treated below.) And finally how is it that taxes are levied on one and all, regardless of whether they voted or not, or, more particularly, whether they voted for the winning candidate? How can either nonvoting or voting for the loser indicate any sort of endorsement of the actions of the elected government?
Neither does voting establish any sort of voluntary consent even by the voters themselves to the government. As Spooner trenchantly pointed out:
In truth, in the case of individuals their actual voting is not to be taken as proof of consent. . . . On the contrary, it is to be considered that, without his consent having even been asked a man finds himself environed by a government that he cannot resist; a government that forces him to pay money renders service, and foregoes the exercise of many of his natural rights, under peril of weighty punishments. He sees, too, that other men practice this tyranny over him by the use of the ballot. He sees further, that, if he will but use the ballot himself, he has some chance of relieving himself from this tyranny of others, by subjecting them to his own. In short, he finds himself, without his consent, so situated that, if he uses the ballot, he may become a master, if he does not use it, he must become a slave. And he has no other alternative than these two. In self-defense, he attempts the former. His case is analogous to that of a man who has been forced into battle, where he must either kill others, or be killed himself. Because, to save his own life in battle, a man attempts to take the lives of his opponents, it is not to be inferred that the battle is one of his own choosing. Neither in contests with the ballot—which is a mere substitute for a bullet—because, as his only chance of self-preservation, a man uses a ballot, is it to be inferred that the contest is one into which he voluntarily entered; that he voluntarily set up all his own natural rights, as a stake against those of others, to be lost or won by the mere power of numbers. . . .
Doubtless the most miserable of men, under the most oppressive government in the world, if allowed the ballot would use it, if they could see any chance of meliorating their condition. But it would not, therefore, be a legitimate inference that the government itself, that crushes them, was one which they had voluntarily set up, or even consented."

" Many anarchist libertarians claim it immoral to vote or to engage in political action–the argument being that by participating in this way in State activity, the libertarian places his moral imprimatur upon the State apparatus itself. But a moral decision must be a free decision, and the State has placed individuals in society in an unfree environment, in a general matrix of coercion. The State—unfortunately—exists, and people must necessarily begin with this matrix to try to remedy their condition. As Lysander Spooner pointed out, in an environment of State coercion, voting does not imply voluntary consent. Indeed, if the State allows us a periodic choice of rulers, limited though that choice may be, it surely cannot be considered immoral to make use of that limited choice to try to reduce or get rid of State power."
