Question: Can you give to someone else a right that you don't have?
Here are your two possible answers:
YES, I can delegate to others a right that I do not have. That would mean that even though it is immoral for me to do certain things (committing theft, assault, murder, whatever), I can nonetheless bestow moral permission on someone else, giving them the moral right to do such things.
Again, I hope I don't have to go to great lengths to explain why such a notion is utterly insane. If you don't understand it, don't worry; I'll just bestow upon someone else the right to bludgeon you with a club until you understand it.
(There is a slight variation, which is equally insane, which is the idea that one person cannot delegate a right he doesn't have, but that multiple people can delegate a right which none of those people possess. This is about as rational as saying, "No, I can't give you an apple, because I don't have one, but if I get together with some of my friends, none of whom has an apple, together we can give you an apple." Right.)
So that answer stinks. But here's the only other option:
The people called "Congress" have no rights that I don't have, and that you don't have. Who could have given them such rights, if no one can delegate a right he himself doesn't possess? If I have no right to "tax" my neighbor, and you have no such right, who could possibly have given the people called "Congress" such a right? In short, no one. You and I have no right to enact and enforce arbitrary "laws" on our neighbors. And neither do the people called "Congress," because no one had the power to delegate to them such a right. You and I have no right to rob people, assault people, threaten people, etc. (We can only rightfully use force to defend against an aggressor.) Ergo, the people called "Congress" have no such right to rob, assault, or threaten either, even if they call it "taxation," or "law," or anything else.
Sorry, statists, but once again, your choices are either believe something insane, or abandon your statism; either you can give someone else the moral right to commit theft, assault, and murder, or "government" is completely bogus, because the people in "government" have no right to do anything that you and I do not have the right to do (because no one has ever had the ability to give them such a right).
Once again, the insanity underlying statism is pretty darn easy to expose, even if it's rather uncomfortable for the indoctrinated to rationally consider. (Again, I was raised as a statist, and I vehemently resisted such obvious truisms for a long time, before giving up and choosing sanity.)
(I'm tempted to end by quoting huge chunks of "The Law," by Frederic Bastiat. But I'll settle for this tidbit: "But how is this legal plunder to be identified? ... See if the law benefits one citizen at the expense of another by doing what the citizen himself cannot do without committing a crime.")
