You ain't debunked shit.
Luffy even now can't even take a base bagua
Hakai was going to kill all 5 to the point midds tsundere ass thanked zoro for what he did
Luffy has taken on bagua on screen even while warming up and sloppy at the begining of the fight, and has fought Kaido for 30 minutes since.
Luffy warned the rest (wasting time) and was prepared for the counter attack before anyone, shocking Killer and going out of the detection of
everyone else until he was in melee range with Kaido. Killer's assertion that they wouldn't be able to dodge is debunked by his subsequent shock at Luffy's speed and ability to cover distance, which anyone who has read One Piece should know about, jet rocket's range and speed are nothing to joke at.
Midd would have been injured as would have the others had they tried to block together, but Luffy alone could have evaded, especially if he hadn't warned everyone giving them precious moments to deal and prep with the situation.
