I still prefer to own movies I like and I have many of them. (no, not SO many as YOU have, my adversary). I think that having them will allow me one day to stop paying constantly more and more expensive subscriptions. By the way, for me, the DVD standard was very strange. I think that the engineering industry works differently than IT/CS guys. They think of "a product" which consists of the medium AND the "protocol"…
Also, DVD is still a standard in medical imaging, which baffles me, because many people do not own drives anymore, but I think this is as close to "owning your own test results" as possible. I cannot imagine someone saying "sorry, you have not extended your subscription to our health-cloud and your results are gone"
