It seems like most bookshop owners today are hoarders-turned-entrepreneur. They rent a storefront, adopt 2-5 cats, and they set up shop with their hoard of books so that they can hoard on a commercial level that would never be possible in a private home.
It also seems that American society has been swept away by the worship of books, rather than literary appreciation or promotion of education. "Banned Books Week" as the primary exhibit here. A tug-of-war over books that are supposedly "banned" when the verb itself has been twisted beyond recognition. I see posters and television shows and public service announcements that promote "Books!" and "Reading!" for no other purpose. Many books are trash and they will fill your head with garbage as sure as social media can, so why the indiscriminate worship of books?
It is conspicuous that, aside from established booksellers, and perhaps the LFL owners, many of the people crying out and moaning over book-destruction seem unwilling or unable to actually take those books in and store them. That is the point, that these books are unworthy of taking up storage space, which is an ongoing cost, and maintenance, and therefore, it is fiscally responsible to sell them, scan them, and destroy them. If you want to dedicate a room full of shelves to books that nobody will ever read, then go ahead and buy out your local bookseller! They will not stop you or cancel your order! Tell them you are saving those innocent books from the Big AI Bugaboo! They'll grovel at your feet!
Also now, I'm seeing small booksellers who feel "suspicious" or "skeptical" about large book orders. There was one Down Under who said "oh we got an order for over 70 and we can't physically handle that!" I feel like it's becoming a "shut up and take their money" situation. These booksellers, as professional business owners, should know that they may never liquidate stock, and this is their golden opportunity to simply get rid of some of that excess hoarded inventory.
But if you're merely cosplaying as a bookseller, and deep down you're a hoarder and a worshipper of books, you may really be reluctant to do transactions or earn money that sells away your books.
