Yes, I agree this is what ownership means in principle. I think the more practical view of ownership is what the current monopolist of violence will let you do with what you possess. The monopolist of violence in most cases being your local government.
There are many real-world examples of being regulated in what you can or can not do with what you ostensibly own. Whether that's real estate, natural resources or intellectual property. Even IP has expiration dates defined by regulators. Do those expiration dates incontrovertibly define what is morally right or wrong to do with said IP? Were the regulators directed by divine mandate when setting those expiration dates?

Just so I'm fully aware of what we're currently debating, is it this?:

In which case, here's an example in which I personally believe theft is morally justified. Let's say your family is caught in a natural disaster, and you need fresh water to survive. A local opportunist saw the disaster coming and stockpiled all local water sources at low prices, and is now attempting to sell you water for the reasonable sum (when compared to the alternative option of death) of your life savings.
I'm curious about your position on this (intentionally extreme) example. Not as a trick question, but because I'd like to know how rigidly you adhere to the concept of ownership being morally just in all cases. If you still believe theft is morally wrong in this case, that's fine - it just means we believe opposite things.
