Ownership, when it extends beyond individual brute force, is always a social convention. More than a "right" to such, society inevitably examines and challenges its social conventions. (There are some long term patterns, but even these are not steady-state.) Society is going to look for what works for society. If and as (over-) concentrated "ownership" increasingly holds society back... In other words, ownership at a societal level is a useful tool, but it is not an absolute. As just one small example, even within our "ownership" society in the U.S., we increasingly have law enforcement confiscating assets without due process whether upon real or convenient suspicion of wrongdoing (asset "forfeiture"). You own it... as long as society says you own it. One reason to use it to help promote a healthy and reasonably fair society -- it's in your own long-term interest.
