Earlier quoted context omitted.
First of all, vinyl is still relatively niche in absolute terms. Second of all, the popularity of vinyl, such as it is, has absolutely nothing to do with availability. It's largely driven by a kind of retro nostalgia (as the technology itself is, of course, inferior from a technical sense of faithful reproduction) plus a desire for personal physical ownership of something.
> It's largely driven by a kind of retro nostalgia Incorrect. The reasons why vinyl specifically is still relevant (as opposed to any other "retro" audio format) are technical. Vinyl avoids compression issues by design. (Compression both in the computer science sense and in the audio engineering sense.)
I don't know what kind of "compression issues" you're talking about but I strongly suspect you'd be well served by learning about the Nyquist–Shannon sampling theorem.
