I can relate to this. Recently I have been giving some of my things away to my parents. Last time they came down to visit I gave them some speakers that were collecting dust---I only use headphones anyway. I also only have two plates, two glasses, two knives and forks now. It forces me to clean up after myself immediately.
Despite this my place is quite cluttered with papers and books that accumulated over the years (I used to study). I don't have a bookshelf so I sort of threw them on a pile in the corner of the room. One day it will be interesting to do an archaeological dig through it. Realistically though I could probably throw it all out without looking.
Sometimes I wish I could just get rid of everything except my bed and computer. I think that impulse arises because I find aspects of the world so complicated and exhausting that I want to at least reduce complexity in what I have control over. Complicated and/or poorly designed things can make me feel uneasy to the point where I avoid them entirely. "Things" can be anything---websites, user interfaces, shops, events. You can't avoid them all though, I wish I never had to do anything.
