The human would only be considered the core in such an instance because the chakra resides in them, thus everything surround it (the body) would be encapsulated as well.
Your ignorance is astounding. I've already said the humans being the core is a possibility, not factual. I'm not attempting to prove my point to you, but rather to disprove your view. From the very beginning you've dismissed any possibility of any other opinion other than your own, thus you believe your view is the only true one and thus factual.
Your only argument to support your point at that time was that since no one has ever attempted to use Planetary Devastation on a human, then it must not be possible. This kind of logic however stands as

, thus it isn't viable to use.
You then give your opinion on how you think the technique works, further pushing it as factual without any basis, but I'll go along with it because it is easy to counter. You believe that Sasuke makes chakra the target for Planetary Devastation. Humans have chakra so Sasuke can target this according to your theory. Just because this chakra is in a body does not mean it can't become a core. That is akin to saying that if a Tailed Beast was in a box Sasuke couldn't target it, which is retarded in every way possible.
Above all, since hosts exists, like Naruto who carry Tailed Beasts, you would have to fully accept that Planetary Devastation could be used on him because he has this mass of chakra you deem a requirement. I'm going to assume you'll be unable to bring anything new to the table and just spew more nonsense about "speculation", so I'll probably just let this thread die off now.
