There's a very particular pain you get when you know you had something and you lost it; or worse, you know you threw it away.
It may be related to too good of a memory, or autism, or whatever, but there are parts of my life where I have way too good a memory for everything I have and had, and other parts where I'm like "yeah I got a lot of something like that, but who cares".

Losing one glove is certainly painful, but nothing compared to the pain, of losing one, throwing away the other, and finding the first one again.

It probably does stem from some sort of loss aversion. We have all wished for longer undo history, things like git take that to the extreme. Now that we can't lose things, we're free to work without that fear.
