Ok, so you didn't understand the argument. Murder is not a freedom, it's an act of violation, which is an anti-freedom act, a non-freedom, because it violates freedom. A freedom cannot violate freedom, that makes no sense. Just because you're able to do something doesn't make it a freedom. Saying you're against certain "freedoms", like murder, is the same as saying you're against certain acts of "love", like rape. It's just not that.

What you're calling "freedom" is merely ability. And what's the difference between the ability to commit murder with governmental law or without it? Nothing. People commit murder all the time now. With law, if you commit murder, a group of people with guns will attempt to hunt you down, and in a free society, people can still do that.

The only difference is words on paper in an office in Washington. Anarchy doesn't mean there are no consequences for one's actions - natural law enacts consequences through other people, just like man's law does.
