>Most people older than 40 got a record players decades ago
That seems unlikely. I'm in my mid 40s and I bought my first music on compact cassette, but that was almost immediately supplanted by CDs. I never owned a record player.
I think that's closer to being true of people over 60. I'm almost 40 and never even came close to owning vinyl, it was all already CDs when I was young and cassettes before that.
People who don't move on a regular basis don't really take the time to assess what it is worth keeping or not.
