Libertarians, by definition, believe in the superiority of liberty: the negative right to be left alone -- in one's person, pursuits, and property -- as long as one leaves others alone. Libertarians therefore believe in the illegitimacy of state-enforced values (e.g., income redistribution, censorship, punishment of "victimless" crimes) because they are inimical to liberty.
Some libertarians (minarchists, such as I) nevertheless believe in the necessity of a state, as long as the state's role is restricted to the protection of liberty. Other libertarians (anarcho-capitalists) argue that the state itself is illegitimate because the existence of a state necessarily compromises liberty. I have dealt elsewhere with the anarcho-capitalist position, and have found it wanting. (See "But Wouldn't Warlords Take Over?" and the posts linked to at the bottom of that post.)
Let's nevertheless imagine a pure anarcho-capitalist society whose members agree voluntarily to leave each other alone. All social and economic transactions are voluntary. Contracts and disputes are enforced through arbitration, to which all parties agree to submit and by the results of which all parties agree to abide. A private agency enforces contractual obligations and adherence to the outcomes of arbitration. (You know that this anarcho-capitalist society is pure fantasy because a private agency with such power is a de facto state. And competing private agencies, each of which may represent a party to a dispute are de facto warlords. But I digress.)
Now, for the members of this fantasyland to enjoy liberty implies, among other things, absolute freedom of speech, except for speech that amounts to harassment, slander, or libel (which are forms of aggression that deprive others of liberty). But what about speech that would sunder the society into libertarian and non-libertarian factions? Suppose that a persuasive orator were to convince a potentially dominant faction of the society of the following proposition: The older members of society should be supported by the younger members, all of whom must "contribute" to the support of the elders, like it or not. Suppose further that the potentially dominant faction heeds the persuasive orator and forces everyone to "contribute" to the support of elders.
Note that our little society's prior agreement to let everyone live in peace wouldn't survive persuasive oratory (just as America's relatively libertarian economic order didn't survive FDR, the Constitution notwithstanding). Perhaps our little society should therefore adopt this restraint on liberty: No one may advocate or conspire in the coercion of the populace, for any end other than defense of the society.
Why an exception for defense? Imagine the long-term consequences for our little society if it were to dither as a marauding band approached, or if too few members of the society were to volunteer the resources needed to defeat the marauding band. What's the good of the society's commitment to liberty if it leads to the society's demise?
Now, the restraint on speech and the exception for defense couldn't be self-enforcing. There would have to a single agency empowered to enforce such things. That agency might as well be called the state.
Here, then, is the paradox for libertarians: Some aspects of liberty must be circumscribed in order to preserve most aspects of liberty.
Note: My free-speech example is just that, an example. I'm not proposing any further restrictions on freedom of speech in the United States, which already has been restricted too much, notably in the realms of commercial and political speech.
