Why don't you try to have a base for your claims instead of just using your opinion?
1. Doesn't matter.
2. Not able to be absorbed. Kaguya would bring him to the gravity dimension and render him unable to cast the animation for Shinra Tensei. They're infused with Senjutsu, so it's breaking through the TSB's.
3. In what world? The same universe where this attack busted through Perfect Susano'o? Shinra Tensei is overpowered, it's not even chakra so absorption won't do anything and if it broke through PS, a superior, more durable construct, then TSB's get smashed.
1. I'm assuming you're conceding here
2a. This is were your falsified opinion comes in. As far as description goes, the Rinnegan can absorb any chakra(or "nin-jutsu" as said by the DataBook). All Killing Ash Bone is classified as nin-jutsu, therefore the Six Paths can take the molecular-level destruction ability away.
2b. I'm not going to argue in terms of scenes, because that's not how this started. The fact is that one attack, Almighty Push, counters another, All Killing Ash Bone.
2c. This is also opinionated. Even if this were to be true though, it doesn't simply pass through easy. The collision would change the direction of the attack's pass.
3. If it's not chakra-based for what-ever reason, then Almighty Push, based on gravity, easily changes the projection of the wind. Naruto was also using his own Truth-Seeking Spheres to counter-act the attack If I am remembering correct, so that puts your last sentence to rest.
