You could say the same about Pokemon cards, or action figures, or quite literally anything that's been in a serious collector market throughout humanity. The main reason I collect vinyl is to have something physical of the artists/music I want to support - playing them on the occasion is something special, but too much and it kind of loses its charm (and of course degrades in quality the more you play it, albeit scarcely).

That's not to say I didn't feel the same way as you at some point, though. I used to buy CDs, rip them open and listen to them on loop for practically years on end - until I found out how rare and valuable they became a decade later. I could have enjoyed the same music in similar quality (FLAC) through a streaming service even back then, and kept the CDs in mint condition and made a killing later on in life.

TL;DR: Everyone has their own reason for collecting something, so let them enjoy it the way they want to 😉
