But you need equipment to actually play?
I’m not a guitar collector/fetishist at all, but still need at minimum an electric (preferably at least two for humbuckers & singlecoils), a steel string, a nylon string and a bass to be able to play what I want to play. Not to mention amps, pedals etc. And this is strictly for playing gigs and home practice, when you get into home recording it piles up even more. Even if you restrict yourself to things you actually use, the possibilities for hoarding are pretty much endless.
Something like this could get interesting
