I honestly don't get the obsession with physical media
Pretty straightfoward. And understanable IMO.
If I have a physical disk of something, I can put it in a compatable system and play/watch it regardless of whether my internet is out or just shitty in general, even years down the line (as far as I'm aware, the devs/company have yet to be able to register/tie disks to devices, and they're not gonna break into my place and take my media away. So while I don't own the thing, my copy is my copy to do with as I please so long as I'm not passing it around for others to download). It's also not tied to any account, so my use of the thing doesn't hang on whether i have a Steam account or a Netflix account or whathaveyou. There's also media preservation, and just the fact that some people like to have something tangible that they can say "this is mine".
Discrot and failing hardware is a problem...but personally, as long as I have a receipt or proof of purchase for it, I'm not gonna lose sleep over getting it from alternative sources if i can't rip the data off the thing myself. It's simple: the company gets my money, they give me a copy of the software, and that's it. What they do with that cash is not my business and what I do with that copy (unless I'm either illegally distributing it or reverse engineering it for my own profit) is not thiers.
