This also covers the right to leave (which I agree is very important, but still covered by property rights)

Right to property is the most important. This is because this covers all other rights. If one believes in self ownership and your body is yours and all that it produces is yours, all rights are covered under this one idea. That is - You own yourself! You own yourself, your body and all that it produces. You own it absolute! No exceptions, no contradictions. any right you can think of comes under this one idea. You are free to do what you wish with your body and all that your body produces so long as it does not harm another's body or property. This covers free speech, it covers the right to life, the right to persuit of happiness.
Just one simple idea - You own yourself and are free to do what you wish so long as it does not harm.

LIFE!..."to be or not to be" all else is derived from that point.

What right do objectivists say is the most fundamental? I ask because I know an anthropologist who says it is the right to leave.
