I can't imagine wanting something even more outdated and obsolete just to put it on a shelf. Why don't the hipsters go for something real old school and insist on wax cylinders?
Believe it or not, vinyl's outsold physical CD sales in the US last year. It's a booming industry, and not just for the hipsters. Tons of the vinyls coming out now have lots of collector's bonuses.
I collected records until about 2006; you could find the occasional vinyl here or there, but most modern releases were rare or hard to come by. I quit simply because it was so expensive and I moved to purely digital music. I do get why people enjoy it though -- there's something raw about the sound. It's not the pure, clean audio of super-mastered digital collections; rather, it's raw and rough and that adds something (depending on context, for example).
Some of my favorite bands were best when they used shitty recording equipment and recorded it all in a garage or little studio. Then, once they get big and can afford a full studio and mastering, there's something sometimes lost. Not always the case, but I've seen it happen.
But yeah, it's interesting to see the confusing renaissance of vinyl.
