Trust me, I suck at tidying and have a cluttered mess, so I'm not being Marie Kondo here.

Your logic works but only so far. If you put nothing "away" all your "working surfaces" will eventually be covered with crap -- except of course it's not crap, it's your things that you intended to keep easily at hand. It'll make it so that it's a chore to find things and also a chore to have a useful space to actually DO anything. Sure, leave out a set of favorite often-used stuff, like say, bread on the counter instead of away in a pantry, your most-worn shoes on the floor by the door, whatever. But curating that set of stuff that is important enough to be "just left out" is important, and it's a REAL challenge for me!!
