Earlier quoted context omitted.
Your conception of vinyl buyers is very negative. I think there's another category of people that buy vinyl. If you really love an album and want to support the artist you can purchase the vinyl version of the album. Apart from supporting the artist you often get additional treats like a nice booklet with the lyrics or additional art/imagery. I really think there's extra value in buying vinyl apart from it being hip.
If you want to buy a physical medium then CDs are the obvious option because objectively they are superior to vinyls in every aspects and they can also come with nice booklets. I think that the hip-value of vinyls is extremely important. I write that as someone who had no choice but use vinyls and tapes until I got a CD player...
The best of both worlds in my opinion is a vinyl + code for a digital copy, which seems to be the direction most have gone for.
