Books and comics alone are a huge problem for me when moving. All of my games, CDs and movie discs could probably fit in 4 cardboard boxes, in comparison.
Music and movie consumption occupies very little of my free time these days. I used to get movies I liked on DVD and BR, but I rarely bought new stuff even in those days, and it's been literally years since I last bought a BRD or a music CD.
Paper is the one physical media I have some sort of addiction to. But even on that front I've reduced my purchases more and more. Physical editions that are really worth the purchase over their digital version are probably luxury editions that take a lot of space and weight a ton, at this point. I rarely find a good reason to buy a paperback these days, if it has zero illustrations and it can be found on ebook. Printing quality has generally degraded enough that e-ink will basically offer the same readability, and with ebooks you can change the font if you want (the choice of font in printing has quickly become somewhat of a dying art, too).
The big question is, how much of your physical media will you consume again in the future?
Possibly half of the books I own I've read only once, and I have no urge to re-read them. Sometimes I think I still own some book I actually got rid of years ago, and whenever I browse my bookshelves I'm reminded of some book I didn't even remember I have. Not a few of the books I've bought, I've never read at all. Just like I have physical music and video that I've bought and never took out of the box. Just like I've bought several video games that are still sealed.
Kojima's movie collection is impressive in pictures, but… it's just a collection. As are most collections you see on YT videos talking about games, movies, music, books. All of those people, all of them, will never consume again 90% of the physical media they have. And, as small as my possessions are compared to theirs, the same applies to me.
BRDs and CDs may still make sense if you care about top audio and video quality vs streaming, but it's rare now to get physical versions that offer content that hasn't been tampered with somehow. Most records have been remastered, and not always for the better. Most movies have been regraded, cleaned up, edited, and/or there's different versions around and it's not easy at all to know which one is the most faithful to the pre-digital era versions. Even books are being edited, see the debate about Roald Dahl's books.
I guess my bottom line is, as much as I like physical media, I already have too much of it that people wouldn't know what to do with in case I die. And I'm actively trying to not increase too much the amount I already own, because in the end most of it is very ephemeral, and I don't really care that much for at least half of what I own, if not in my fond memories of a past self that doesn't exist anymore. Like we've said in this thread, most of it is about rituals and the sense of identity and meaning that owning something gives you. And I think this has very much to do with the renewed interest in physical media that is happening. People want to have something to show off, something that represents what they believe they are and stand for. Turns out that owning nothing probably won't make us all that happy. But in no small part, it's still a way to fill a void. At one point most people will realize that their turntable and vinyls aren't getting as much use as the compressed digital version of the same music on their phone. But those will still look cool on their shelf, and they'll have a story to tell and some background for their photos.
