Yeah I mean many people with disposable income seems to be doing this, it's just that the music community has a name for it, GAS, and it's a bit of a meme in the community.

I have a friend who seemingly collects mechanical keyboards. He keeps saying he needs them for various purposes, but always seems to be using the latest one, then the old ones go up on a shelf and sit there.

Another friend is obsessed with football, so he has a bunch of shoes, also "depending on the grass/ground" yet keeps using 1 or 2 the most, the others seems to in some cases be "collectors items" and never gets used.

Another friend is a avid golfer, literally has a wall in the garage with clubs, but seems to mostly stick with the clubs they have in their go-to bag.

I'm sure I could come up with more examples, it just seems pervasive among all people who can spend money on their hobbies.

I have a friend who plays tennis. He literally has like 100 tennis balls, all neatly packed and sorted on a shelf. Of course, all you need for a tennis match is like 3-4, since more won't fit in the pockets anyway.
