Oda doesn't need to hope for that its clearly working
Leddit and twatter full of people that say I will buy "2 copies" of the novel from zolo that oda is not even bothered to write
I didn't even know a law novel exist too, I just can imagine how much money oda made with that with all the law fujoshis buying it
The fanbase of OP is extra cooked, when Kishimoto released those gaiden things there was at least backlash that he put all the kakashi writing and stuff into some shit book by his assistant. Which is still more effort btw.
