I think there's an argument for doing those things yourself if it's genuinely cheaper or of higher-quality, but you can't realistically make that argument with vinyl.

I think with vinyl people are looking for more of a sense of ownership. It doesn't feel like you own an album, and don't get the feeling that it contributes to some part of you, when you click "save" in Spotify. It doesn't take any effort or any sacrifice (money) to do that, so it comes with no opportunity cost. But buying a record is more deliberate and usually means that your ownership of it comes at the expense of something else you'd instead buy with that money.

I admit it's a pretty wishy-washy argument, but for most people, the prospect of buying a vinyl record has to be rooted in something psychological because objectively speaking there aren't very many good arguments for it.
