I was never debunked, that's wishful thinking..
What matters when analysing a new power is the contextual story implications.. When has AdCoC been revealed for the first time, Chapter 1010,1011.. Luffy, Kaido and Big Mom used it by no touching their opponents.. The notion can not be discredited..
He did with pure Haki blast attack from Enma KoH..
Pushing Cushion or Pressuring the immediate personal range.. That's Materializing CoC..
He's training and keeping his distance on purpose.. Luffy touched Kaido with Red Roc and he used Internal Destruction CoA there..
Internal Destruction CoA is an offensive capability, Only CoA emission is defensive and used as a shield..
