East blue and early pre-timskip Luffy had a bit of complexity to it, still goofy and cringe, but at least there was something going on for him, with future character development potential.
There is complexity here too.
His anger at his weakness before leading him to fight Fujitora
the compelling desire to overcome Katakuri,
stubbornly waiting for Sanji with 100% belief because he "couldn't become pirate king without him"
being the only one to challenge Momo in multiple points to bring out the best in him,
great dialogue to not letting Jinbe die
telling Tama about Ace's death
being the only one confident on the rooftop of their victory
He telepathically contacted people without VoAT, something no other creature or being has done,
laughed while grabbing Kaido and telling Yamato not to interfere in his 1vs1 to become a true Yonko caliber character.
Now you have chapters with him laughing but having a deep seriousness undercutting it as shown in this chapter.
most likely has an interesting awakening to come (gomu gomu no what?),
