I have no interest in vinyl records myself these days, but I know there's still a largish market for them, and again what's the problem? If that pleases some people? That's exactly what music is all about, pleasing people. And I can understand that the medium can play a role in the whole experience.
If you take "pleasure" out of the equation, then you can eradicate music as well, it's not "useful", right? And maybe we can go further and say that all this *has* to go anyway, because it's consuming resources while not being strictly useful. Yeah, we'll save the planet.
Just a thought. Not everything we do in life has a strict utility factor. Life would be pretty dull otherwise, and the idea of *enforcing* utility everywhere is a totalitarian idea.
