What libertarians propose is that all coercion be in defense of property ownership. This seems "fair" until you realize that "property ownership" is itself a complex historical object. The feudal system is named after a form of property ownership - the feodum or fief. The colonial system created property for Europeans by appropriating it from natives. The system of slavery was also based on a certain kind of property definition.

Saying "don't use coercion except to defend legitimate property rights" is like saying "don't use military force except to defend against legitimate threats." It seems like common sense, but all the complexity of politics is swept under the rug in these phrases "property rights" or "threats". In my view, no one is born with a "right" to property, property is just a concrete representation of the political equilibrium that exists at a certain time.

Most property in the world can be traced back to an original owner, from whom it was stolen (war, colonization and similar events). That original owner might have stolen it from someone else.

But that is a completely different point, that really has nothing to do with libertarianism, or any reasonably capitalist society, where property ownership is permitted. It's my impression that a symptom of a mature capitalist society is that historical property disputes are settled in a sense that can be considered fair. That someone might not accept property rights is an interesting discussion, and it certainly rules out any form of capitalist system, but it doesn't really apply in this discussion.

Nobody is born with a right TO anything, but rather a right to NOT be coerced. The consequence of this is that you have the right to do whatever you want with your property (which includes your body and anything you do with that, i.e. work), as long as you don't interfere with other peoples right to do the same - i.e. coerce them.

One important distinction between libertarianism and anarcho-capitalism is how to resolve conflicts that will inevitably be over property. A-C doesn't accept any state-like structures like police and courts, but libertarianism does, and the only people that get to coerce other people physically are the police, answering to the courts.

a) Property rights are a form of coercion.

b) 'Property rights' is a wide umbrella under which almost any form of coercion could be justified.

b) If the enforcement of property rights justifies coercion, then almost any kind of coercion can be justified if the prevailing property system is chosen correctly. For example, if a totalitarian state were to have a system where everything belongs to the state, including the citizens, then it would have the right to do whatever it wants with its property, and any assertion of personal freedoms would be theft.

b) If someone is free too coerce anyone he owns, and he can arbitrarily choose who he owns, then he is free to coerce everybody. It's a tautology, but not a very useful one.

b) The point is that the concept of property rights is mostly vacuous unless you specify which system of property rights you are speaking of. cia_plant was pointing out that what one person considers oppression, another might consider fair use of property. Therefore any state can be considered libertarian unless you specify restrictions on what counts as a valid system of property.

Since all people need to be cared for until a certain age, all people who survive past the first few days of their lives are born into coercion under a strict meaning of the word. Some would escape by living as hermits in desert land or remote islands that nobody cared to enforce law on. Hell - if you're going to be a pedant why restrict it to human coercion? The weather itself is a form of coercian. As are the laws of physics themselves.

Although in a strict sense you're right, I think you're wasting time. However, I have a morbid curiosity for some things and would be genuinely interested to learn what axe you're grinding.

Well - gravity.

I mistook your motive. I've read the thread a few more times and see you've been quite specific in your responses.

I was born with a right to not be coerced by gravity?
