Discuss the benefits of trying liberty rather than statism as the basis of a society* and you will hear many people drone on and on about how it won't work. One common example is the "Somalia blah blah blah" retort. As if that has any bearing on what a free society would be.
When liberty is given a real shot we can then discuss the results.
Even if anarchy or an other wise free society is "unworkable", that doesn't mean the statist alternative is right. Statism is also unworkable, as has been shown amply throughout recorded history. To deny that statism results in calamity is just silly. Plus, based as statism always is (by definition) on theft and coercion, it is wrong.
Given the choice, I would rather live in a failed society based upon liberty rather than an equally failed society based upon authoritarianism. Liberty is right, at least.
If liberty also fails to produce a workable society, then the obvious conclusion is that society itself is the problem. Maybe society* is a false concept and can never be truly workable.
*I am using the term "society" as short-hand for the interactions of all people who actually deal with one another in some way, not as some real, physical thing (like some collectivists seem to believe).
