The thing is that chances are I won't ever reuse any of it but I keep it around just because it might be handy in the future.

I do the same thing. I just moved, and was putting up a towel rack. Due to an unfortunate miscalculation, I got a slightly wrong size of plastic drywall anchor thingy. The old screw didn't fit. The new screw had a head on it that kept the decorative cap from fitting properly. I left the cap off. A week later, I was (finally) clearing out a bunch of "junk" that I'd been carting around for a dozen years, or so, because "I'm honestly never going to use any of this stuff." I found a screw that fit. I couldn't bring myself to throw out any more stuff, because the idea that 'it might be handy in the future' was just validated.
