It's not ad hominem, I'm just basing myself on what you've been defending on this thread: the use of violence to force people to adhere to your regulations and taxes. You're defending the state, so by definition you're supporting violence.

And who said "no rules"? Freedom is about no rulers, not no rules. This has been said more than once on this thread too. This is such a repeated topic when discussing libertarianism that when I had the chance I wrote a text about it myself. It is in Portuguese, if you don't mind an auto translation: http://tinyurl.com/6jplv8u
Of course you can find better material than that. The short book Chaos Theory, from Robert Murphy, is easy to read and good. There are also plenty of videos like this (very good video this one).

Since I'm giving links, one that you shouldn't miss is this nice short animation on ethics: http://www.isil.org/resources/philosophy-of-liberty-index.html
It was actually this animation that made search for more answers concerning libertarianism. When I first saw it, that put me in a sort of contradiction, since I couldn't disagree with its fundamentals, but at the moment I couldn't agree either with the conclusion of such fundamentals. So I went on reading and learning about ethics and economics, until I changed my mind in many aspects.
