People get a weird sentimental attachment to stuff. I used to have a lot of books, and looking through them would give me a good feeling, though I rarely read them. Got rid of most of them and haven't noticed their absence. But it feel bad getting rid of them. I can see why people accumulate a lot of things they never use, and why it looks weird from the outside. But, I don't want to end up on that 'Hoarders' show.
