The logic is pretty simple. Boruto Novels are canon because they are included in the official timeline, illustrated by Ikemoto, and based on the anime which is currently being directed by Yamashita...
You don't have the justification to say the novel and anime doesn't follow the Manga, when Manga started from Momoshiki arc, and neglected the preceding events. The novels are mainly based on the events that happened prior to Momoshiki arc, so you can't make your claim somewhat entitled.
Here's an analogy to proper relay the point; There's an imprint of an unknown animal foot visible on the ground. A zoologist make notes of this, and decide to follow the foot prints of this animal.
The zoologist however changes his mind, and did not follow the foot prints at all.
Now would you say the Zoologist isn't correctly following the foot prints of the animal, when he didn't begin officially..?
The statement he didn't follow the prints correctly is only true if he had began following the prints, and changed course because he saw the foot prints of another animal entirely.
The anime, and the novels did not start from Momoshiki arc. They started prior to that arc, so they were never trying to follow the Manga, but covering the events the Manga neglected.
There's nothing obsessive of trying to consider the novels canon. By definition, Obsessive describes someone who is fixated on one thing, while ignoring the rest variation of that thing. We haven't ignore the Manga version because there wasn't one to begin with. The Manga started from Momoshiki arc, and conveniently neglected everything that happened prior. Thus, the anime and the recent novels decided to cover these events, and by virtue had every rights to be the main condition regarding its canonicity state.
If the novel comes out tomorrow and add things opposing what the Manga or the anime portrayed, then it's non-canon. So far, it hasn't. If anything, the Manga seemed to be adding things initially advanced by the novel and anime.
The recent novels are entirely based on the anime. The events fit with how the anime portrayed them. The novels only differs because it's more detailed, which should be expected for the reason that the novels is descriptively driven.
"The only thing from the anime stated by Kodachi and Kishi, etc. That is to be taken as "Canon" is the Academy Arc, which is the Nue Arc - Graduation. Nothing else"
It's funny because Momoshiki's feat was from the nue arc, by your own admission, it's canon.
Kishimoto never stated he intended to have Toneri on the movie. Sorry to say, for a site proclaimed to have a lot of knowledgeable Naruto debaters, there are a lot of misinformations going around.
"Neither Kishi or Kodachi has anything to do with the Novel"
Kishi actually illustrated the Shinden novels. Kodachi isn't the supreme author, but Ikemoto is. Like I said, he was the one Kishimoto personally gave his series to handle. Ukyō Kodachi most of the times has his inputs overruled.
Again with the self-entitlement. Just because you said it's not canon, doesn't mean it's not canon. Frankly, the assertion shouldn't even be considered seeing as your points is mostly based on false information.
Furthermore,
the anime story has been stated to be supervised by Ukyō Kodachi. Kishimoto even added,
"I plan to even make it better than Naruto." Keep in mind Kishimoto was talking about the anime. The statement implies, Kishimoto is heavily involved with the anime, making it canon.
And the fact the novels are based on the anime, makes them canon. Similarly, they are part of the Boruto Naruto Next Generation official timeline and illustrated by Ikemoto, ergo they are canon.
