I agree that ownership and property rights are an invention - though one of a free society. And you are correct that society can just as easily decide that these rights are no longer valid, though that is not a society I would ever consider free. To a certain extent that is happening already. The day the individual is forced to give up his last right and his last dollar to the ugly greed of the 'collective good' will be a sad day indeed.

Imagine a future where self-driving cars (=home delivery taking over retail), 3D printers, fully automated factories, and the death of copyright/intellectual property has put 75% of the population out of work. It's hard to imagine anything BUT some kind of socialist/communist system required.

Well, I think you've certainly got an interesting notion of freedom. I don't consider a life subjected to the will of a state free in any meaningful sense of the word. You're only 'free' insofar as your rulers choose to protect your interests.

This isn't to say that an ownership-oriented society is bad because it is unfree; just that it is inherently unfree, like any other formal system for living in cooperative groups.

So in my view, the argument for private ownership-oriented societies from freedom falls apart. And we're back wondering why we shouldn't 'steal' from the well.
