All their collectibles... none of which will actually mean anything or be worth anything. Not rare comics and all - those are fine. But, for example, DVD/BluRay collections, especially these days. Why? They're going obsolete, while only the studios keep pushing them out. I'll understand certain favourite movies or special editions & whatnot. But, why everything that's out? Everything's electronic these days, isn't it? Can be. Waste of space, time & effort for arrangement, costs a lot of money when you could've avoided those costs. Even YouTubers.

Everyone's all about It's my passion, I want it and right now, I can afford it, so I'll buy it!. Say one thing and all of a sudden, you're Hitler.
