While I do very much appreciate the left-anarchist critique of private (land) property and rent within the context of what we have today, I completely reject the notion you put forward here, or to which at least I believe you refer.

At the risk of offering the personal example, I used to own three houses in the US, while renting space in a fourth. Those I did not live in, I rented to tenants. In each case, we contracted for the rent and conditions of tenancy. Would there at any time arisen a situation in which my tenants would have been morally justified in expropriating my property? Perhaps, but such never occurred. I didn’t inherit what tenuous and ephemeral wealth I had, but my situation then was such that I was able to control a few bits of land and make a very small profit thereby.

Are there very very many claims of property today existing which are unjust and which should be rightly dissolved? Certainly. Were my claims such? Well, you’d have been welcome to argue that with me, but you can be equally certain that had you attempted to escalate from argument to action I would have met you with every force at my disposal.

Rentiers are parasites and oppressors just as much as government is. Rent is extortion with threats of violence just as much as tax is.
