The Road to "Here"

How did I become an anarchist or a libertarian or whatever I am? I think it was by a careful examination of the way things are, and the way things work. Coupled with a respect for the absolute rights of everyone, even my "enemies" to live free of coercion. I don't expect anyone to respect any rights of mine that I would deny others. If I want to do something I can step back and think "Would I allow someone else to do this?" If the answer is "yes", then I can do it without any guilt. If the answer is "no" then I should not do it or I should examine why I answered "no".
I think the libertarian philosophy is the best for me personally and for everyone else as well. It doesn't "level the playing field" like some other philosophies, but lets everyone choose whichever playing field or hill or valley that suits them best. Only in the absence of coercion can someone rise to their full potential.
It is also the only philosophy that recognizes that every "rule" applies to everyone. No privileged class of overseers who are immune to the rules they impose on everyone else. There is only one basic rule: The Zero Aggression Principle: "No human being has the right - under any circumstances - to initiate force against another human being, nor to threaten or delegate its initiation." This same idea has been stated in many ways by many cultures. "Do unto others as you would have them do unto you"... "An it harm none, do what ye will".. Same message; different words, because this is the one rule that is inborn in us all. It is why children cry "He started it" when they disagree. We all understand at an instinctive level that "starting it" is wrong.
I can't understand why it is so hard for authoritarians to get out of the way of people's liberty. Some people just have a pathological desire to control the lives of those around them, I suppose. It sounds like a mental illness to me. Is there a treatment for that? I know there is an academy where you can learn to escape the chains of authoritarianism.
