If there is something you care about, there is nothing like a physical media copy to ensure you have continued access to the item (and the version you prefer). My only copy of Star Wars is the "Definitive" laserdisc collection. It may be over 20 years old, but it has not suffered the modifications that Lucas made nor the new changes that Disney is making. Once everything is streamed, content owners will be able to modify, suppress, pull from release, or decide to charge you an arm and a leg. It is about control. We fought for the control over 40 years ago and thought we had won. Now the studios are going to get it all back.
