Yes, but there is something to be told for wading through mountains of junk to unearth something notable, I think many book nerds connect to that feeling.
One banana box full of random books: sure. Fun to dig into and see what's there.
Twenty unsorted banana boxes: every book just becomes a blur (as in, “Oh great, another Danielle Steele novel, and another bible, and another Excel 97 for dummies, …”).
I’m not the world’s biggest bookworm but I go to Goodwill almost every week and look through the used books for sale. The most fun part is browsing because I never go in knowing what I’m looking for.
That is only fun because they already cataloged them for you. They made a little collection "used books for sale" with just the right size for you to enjoy browsing through. Now imagine you run into a barn full of books, a couple of containers outside, unsorted, all labeled "used books for sale" and no way to tell which were there last week and which weren't. At best you can visit 1% of the books this week, and next week the same 1%, or maybe another. That's what the issue is here.
Most people do not enjoy that more then once or twice.
