On the other hand even the most advantageous subscription today just eases people into this model which certainly opens the door for far more abuse in the future than straight ownership.
Given where we are today with subscriptions I'd say that battle is already lost. People stopped owning their movies or music (that's after you realize that even having a physical copy doesn't mean ownership), and who knows how many other things. It's just one more software switch for a feature you rent rather than own.
