It's nothing more than having emotional value, not real value.
IMO Ron, there's nothing really wrong with that. As long as the accumulation doesn't become onerous due to storage expense or inconvenience, I don't see a problem.
We have some of the same issues here. My shop is full of tools, materials and do-dads I accumulated over the decades and inherited from my Dad. It's tidy but crowded. Frankly, I don't spend much time tinkering there anymore. Yet, I'm inclined to keep it all. When I do invest a few days in some project, it's really satisfying and I enjoy it.
DW is a quilter. Her "hobby room" is loaded with fabrics, machines and apparatus and we both know she could do without a lot of it. But, who cares? She likes having the stuff, we have plenty of room, so why not?
And there are a few more examples around the house. I won't get started telling about my accumulation of camping and fishing gear much of which could be done without but I still chose to hang on to.
The worse case scenario would be needing to unload everything quickly due to an emergency or rapidly changing plans. I bet we, or the kids, could give much of it away to charity and then call in a local estate liquidator and have the balance gone within a few days. Sure, we'd only get a few cents on the dollar, but taking a loss of a few thousand vs. selling it all ourselves would mean little to us or our estate.
I understand there are extreme cases out there where someone has 200 cases of cat food on hand for their twenty-seven cats, but that's an extreme. Needing to own so little so that a couple can live in an efficiency apartment with room to spare is a little extreme too!
