I think your entire post is tenuose given how a quote can prove your first paragraph completely and utterly wrong.

You're the one that didn't read the article:

"Now, I believe it’s much more useful to say something in this form: this book has this value to this person in this context."

She used to think all books were good. This paragraph shows her current thinking. That all books are still good. You just need to think about it from a different angle/context.

I'm sorry. But saying I didn't read the article is offensively wrong. I'm even inclined to believe that it's a lie. You're just deliberately making it up.
