Physical media isn't dead, you can still buy DVD/Bluray disks for popular content, unless it's a platform exclusive.

So if you really value physical media, buy it and refuse to use streaming services. I rip mine to Jellyfin so I get the same streaming platform experience, while owning physical media. If my kids want to watch something, I order it and rip it. If my internet connection dies, I still have access to it because it's on my local network. If someone wants to borrow it, I just give them a copy (or I can point them to my Jellyfin service, which is also available outside my house).
