While I'm sure there are plenty of vinyl collectors out there with some Displates up, I feel like vinyl has a lot of elements that make its audience significantly broader (even excluding player owners) - mainly that it has a cultural history associated with it.
I also think people generally underestimate "potential playability" or aspirational record player ownership as factors in buying vinyl. A LOT of people who may never own a record player in their lifetime still think they might, & even if they don't their kids or grandkids might. Vinyl collections are heirlooms.
Anecdotal data from my Gen-Z daughter, currently a college freshman, is that they want the cover art. Her dorm room walls are decorated with vinyl albums in frames where they cannot be listened to.
- They want the cover art
- They want a physical token representing an artist they like
- They want to financially support the artist in a direct way
- They speculate they might get a player someday (much akin to book buyers leaving books on their shelves unread for years on end)
1 of the above might be the primary driver for any given buyer but I'd assume all of the above play some part in their motivations.
