There is diminishing importance of ownership as time passes though because there is less and less desire to own such assets as they get older and newer titles come out.
There are exceptions to the rule, but I'd imagine less than 1% of the population cares about owning/emulating PS3 or even PS4 games at this point.
So yes, there is an eventual vector for "ownership" (though illicit, at least in this hypothetical) but I doubt that moves the needle much if at all.
