Sure. If I beat you up and take your bike in the United States, I possess your bike, but I don't own it. That's an easy distinction by example and it is noncircular. The law thinks it belongs to you and men with guns will try to take it from you. How would you describe your relationship to an object in your safety deposit box? You certainly don't possess it. In a world without society, you would have zero relationship to it at all, it has nothing to do with you. All you have are the promises that it will be returned to you upon request and that those promises will be backed up by force of law, enforced by society.

Yes, ownership cannot exist without societal structure, it's a legal term invented to describe something so it's only relevant where law exists (i.e. society), which was exactly my point a couple of posts ago. That does NOT mean that ownership is "possession plus society". It simply means that ownership is a concept that cannot be defined without societal structure.

And it's very often that eggs inside nests get stolen when left unattended. They are food for other animals. How is the frequency with which something happens relevant here? I don't know what point you're trying to make; do you not understand what it means to own something? Do you believe that when you leave your home for work in the morning it ceases to be yours? Do you really believe there is no difference between a crow picking up an object and a contract assigning legal ownership of an object to a person? Is this a Socratic dialogue?
