Vinyl doesn't degrade with time, but it does degrade each time you play it. A heavily played album does not sound the same as a new one. The rate of degradation probably depends to some degree on your specific turntable and needle. (Of course, a worn-out record has its own special charm.)
And I've certainly lost all the MP3's I had from 25 years ago to 15 years ago. God only knows what old hard drive they were on that got tossed. I hadn't listened to them in years, of course, once Spotify's library grew large enough.
If you deliberately throw out your record collection, possibly because you no longer like that style of music that's OK and not the thing we are debating here.
I do still listen to those records from 20 years ago.
We are also not talking about you renting music. That's OK if you decide you'd rather rent your music and are OK to loose access to it at any point in time at which Spotify or a rights owner may pull it from rental access.
We are talking about music that someone bought to own, albeit with DRM because copying. That's OK too but then Sony can't pull something like this without valid outrage being directed at them. The expectation was that I can listen to this in 75 years if I so choose.
