Me committing a Nominal Fallacy implies I'm asserting that merely providing something a name innately explains what it is. I'm not doing that. What I'm doing is relaying already accepted information, by explaining the evidence through the justifications provided. So this is a complete misinterpretation of what I asserted in my post.
It's stated that Training and Experience facilitates the development of spiritual and mental energies, not that they're key components that comprise said spiritual and mental energies. It's tantamount to assuming cells construct human thoughts, and thus thoughts aren't mind-dependent, immaterial properties, because cells are physical particles that develop and constitute the structures needed for thoughts to occur. You're committing a Compositional Fallacy by doing this - by inferring the validity of Training and Experience causing the development of mental and spiritual energies, You then incorrectly assume Training and Experience wholly constructs mental and spiritual energies, when it doesn't as sufficiently explained above.
Now this is a Nominal Fallacy. By asserting it's hyperbolic, you presume that it fully explains why it's hyperbolic, despite the fact that it is not accepted on this site nor sufficiently explained in your post.
We objectively do have direct evidence of this being true. It's explicitly stated that TSO can erase all Ninjutsu and Dan's spiritual body technique is explicitly described as a Ninjutsu in the databooks. Asserting any other conclusion requires us to explain that "all" Ninjutsu doesn't actually encompass "all" Ninjutsu, which hasn't been done yet. Actually explain why Dan's spiritual body technique wouldn't get interacted with and erased by TSO?
It wouldn't because the argument for Minato having his spiritual body returned back into the Pure Lands is contextualized to a mechanic with the Edo Tensei, which is something Dan isn't subjected to because his Ninjutsu doesn't tie his spiritual body to his physical one through a Ninjutsu. It rather simply, astrally projects himself. It would require the TSO to actually hit his spiritual form to nullify the Ninjutsu that is allowing him to astrally project himself in the first place.
