>all of these things are permanently lost

A small fraction of them is saved in the model. Far more is saved in the digitized copy as long as they keep it which they have plenty of incentives to do so (future training of newer models).

That's more than what happens if that book was burned or sent to a landfill, but less than if the book is giving a loving home.

>They removed the pages from the binding, scanned them on a high speed conveyor belt scanner which yielded full color 600 DPI jp2 images, placed the pages back in the binding like a folio that could be re-bound if needed, vacuum sealed them, and stored them in a salt mine.

My understanding is that this simply isn't legally allowed for these books. The original must be destroyed for the digital copy to not be copyright infringement.

>That’s a false dichotomy.

I pointed out there is a spread of possible outcomes and that different people are considering different outcomes and the comparison of if this is good or bad depends upon which outcome one considers. I even mention that both outcomes are sometimes right. That's about as far from a false dichotomy as I can see it.
