Copyright applies to distribution, not consumption. You violate no law when I create an unauthorized copy of a work
This is completely untrue. Making any unauthorised copy is an infringement of copyright. Hell, the UK determined that merely loading a pirated game into RAM was unauthorised copying, making the act of playing a pirated game unlawful - thankfully this is ruling only the case in the UK, however the basic principles of copyright are the same all over the world.
When you buy something, you get a limited license to make copies for the purpose of viewing the material. That license does not extend to making backup copies. However, in a practical sense, it is very unlikely you will be prosecuted for most kinds of infringement like this - particularly when no money is involved. It’s still infringement, though.
Edit: I will say though: you violate no law when you view a copy I create. However I would still be infringing for making and showing you the copy.
In the case of making a book report, that is educational, and thus fair use. ChatGPT is not educational - you might use it for education, but ChatGPT’s use of copyrighted material is for commercial enterprise.
