Libertarians are looking for the American ideal of equality before the law, as guaranteed by the Constitution. Not a "Damn the torpedos" make up law. If that's not obvious from what's been written by libertarians and others then someone has missed the point entirely or is stuck in a rut.
Aside from the fact that it'll never happen, I thought the libertarian ideal was non-aggression in the law. Equality in the law doesn't mean it'll be okay with you guys.
And where does the Constitution control the local governments? I keep raising this argument, but at some point libertarians have to acknowledge the fact that they would be guilty of hypocrisy if they prohibited the people from true self-governance. If a town wants to ban liquor sales on Sunday, can you honestly say that it's wrong for them to do it? Do you allow them the freedom to self-govern, or do you impose your own moral code on them by preventing them from passing legislation that is antithetical to the libertarian ideal?
