I started to sneer at this personification of objects but then realized that if I could only find a good home for everything, I would happily empty out the vast majority of things I currently provide a home for. Near the top of my “win the lotto” list is hiring someone to do just that.
The question of historic value is interesting as most everyday objects do not start out with intrinsic value. They only gain value, if they ever do, when most other similar items disappear. Since there will always be hoarders, you could argue that, to the extent all non-hoarders lived by these de-cluttering rules, items saved by hoarders would appreciate in value at a faster rate.
Related to this, I have to admit that I always feel an instant of perverse envy when I see images of people who have lost everything they own in a fire or tornado. There are so many things that I couldn’t dispose of that I would be happy to see disappear without a trace.
