lmao , Luffy has the tools like Zoro ; his only reaction is doing what Zoro did or he would have been dead but mf couldn't do shit in time and Zoro could ; that's what Hakai feat beside moving faster than Law's finger manipulation .
u got nothing , Hakified Gear 3rd getting used under water .
Also Yamato using Haki while she was sea stoned :
it's just ur ass can't read .
like how he was weakened by using sea stone , and he could his haki since Haki has no weakness related to sea stones or mother nature.
Yamato fights in sea stone hand cuffs and could react to Gear 3rd / 2sd Luffy while using haki and could use adv CoC , u got no arguments u are just pedaling here with the excuses each time
