This as well. Growing up in a house of book lovers, myself included, destroying a book was akin to kicking a puppy. Realistically though, they're ultimately consumables. They're meant to be bought, used, and replaced as needed. With luck the destruction included recycling as much as possible, seeing as it's mainly paper.

To a certain extent I agree, but you can buy a book and still commit copyright infringement by copying its contents (for use other than personal use)

If this would go to court, it would depend on whether training an LLM model is more akin to copying or learning. I can see arguments for either interpretation, but I suspect that the law would lean more toward it being copying rather than learning
