Property rights arise from selfownership (which you literally can not argue against without being selfcontradictory) and from those the right of a worker to his produce.

Oh, but I can. Argue against self-ownership that is ;-) Rights, my friend, do not exist in nature. Ownership doesn't exist in nature. Property rights are a legal construct, enforcement of which is depending on the use or threat of force, be it from the government or some libertarian day-dream of a privately owned enforcement agency; it's all the same. Property therefore is the diametrical opposite of liberty. And self-ownership..? That's a meaningless concept as far as I'm concerned; I do not own myself, I AM myself, ownership never enters the picture. As a consequence, free markets don't exist, have never existed and will never exist. It's also meaningless to discuss or theorize about a free society with absolutely free individuals. The only thing we can do, is try to maximize freedom for as much people as possible, and for that it's best to forget about property altogether, and talk about access to the things we all need. I don't need to own a CD, as long as I can listen to the music I want to hear. I don't need to own a home, as long as I have a place to stay where I'm not bothered by others. The problem is that we've attached those needs to property, instead of mutual respect and consideration. We don't need ownership, we need access. And access doesn't have to be determined by ownership or any other contract. Sure this sounds extremely idealistic (I guess we're both extremists ;-)), but it's in fact the way we used to live with each other in tribes.

Back to capitalism, because I suspect (not entirely sure) that you misunderstand what it is. Capitalism isn't defined by markets, free or otherwise. Capitalism is defined by the private ownership of the means of production. There's a difference between personal ownership and private ownership. To own the things we use ourselves is personal ownership; I have my toothbrush, you have yours. Owning the stuff we all use and need is private ownership; the land, the food, the water, the resources from which we make the products we all need. As far as ownership goes, I can live in a world with personal ownership, but private ownership is exactly what's wrong in this world. The American constitution begins with "We hold these truths to be self-evident," and that's a problem; there are no such things as innate rights. Just like way back when we were tribal people, rights are exactly what's allowed by the community you're born into. Rights are always granted and taken away by your fellow human beings.

And so would a worker coop btw, worker-coops are still capitalist provided everyone thats part of it agreed to be and they dont force themselves on anyone else.

This is another reason why I suspect you don't fully understand what capitalism is; worker-coops can exist withing a capitalist framework, but are themselves the opposite of capitalism. Again, capitalism is defined by the private ownership of the means of production, socialism is defined by the workers owning the means of production; worker-coops are a form of socialism, and if that coop sells their products on a market, it's called "market socialism," which is yet another indication that capitalism isn't defined by free or regulated markets. And in our world several worker coops exist alongside capitalist corporations.

I really appreciate your responses by the way, it's always good to see people who are willing to exchange ideas, thoughts and opinions; it's something that's becoming rather scarce these days ;-) I hope I've explained sufficiently that I'm not "sidestepping" the idea of a free market; it's just something that's not worth expending time or effort on in my opinion. And I'm sorry to hear about your struggles with your health; I sincerely hope you've found a way to manage and exist at peace with yourself and your loved ones...
