I thought the context of my comment made it obvious. Unneeded and unnecessary items cluttering up your home are to me akin to leaves in the garage. It inconveniences me every time I have to step around or over them, clear space to set a drink down, move that box in my closet full of old cables, etc., similar to how walking into your garage with socks on is a lot more annoying if there are leaves and pollen about. I would contend it’s rather less healthy not to notice these things since they subtract from one’s executive function.
