I bet there’s a much larger percentage of gamers who do this, compared to irl hoarders.

I think it has to do with the fact in the game you don’t know what’s coming next. But irl you know you can get more shit at the store next week, so you can throw out this week’s trash and you’ll have more soon.

Though in fairness, boxes and drawers of many things have indeed provided a lot of value through years. I also do lets say yearly cleanups where I comb through things, throw away what hasn't been used to for a while or what doesn't have a purpose anymore so it's not just endless hoarding. I don't just hoard clutter and junk.
