I support the idea of physical media 100%. It's much more dependable, and once the discs are pressed the content can't be remotely/silently censored or edited the way it can on streaming services. If you rip the content yourself there's nobody carefully keeping track of when/where/how often you view what you're watching. You don't get as much privacy with DVD/blu-ray players though. Players that are connected to the internet will phone home and report what you watch. They'll also refuse to play some media until you've connected them to the internet to get updates. Some players like game consoles will even store information on what you watch when offline and collect that data when they have a network connection.
The biggest problem I have with physical media is that increasingly shows aren't being sold at all. Sometimes it's older or genuinely obscure stuff, but sometimes even recent and popular stuff doesn't get released. I suspect that often it's intentionally done to drive subscriptions to streaming services.
There are still a lot of shows that can't be legally obtained anymore. Sym-Bionic Titan (2010) is one I've pretty much given up hope on. There are also a bunch of Disney shows like Star vs. the Forces of Evil, Amphibia, and Owl House that never got a physical release.
Prices on physical media are going down which is nice since a lot of companies played bullshit games like releasing "volumes" or "collections" instead of full seasons and you still have to do some research to know which discs have bad transfers, terrible "remasters", and which should be fullscreen vs widescreen. I recently got a really good deal on Star Trek: TOS, only to later realize that they'd replaced all the special effects and shots of the Enterprise with CGI.
