Disingenuous way to present the question.
Ehh
People want kaido to get up due to believing he still didn't use awakening and all the potential power he had. Along with with luffy's victory using his epithet. Some using the line about hell as evidence
Just about all of that applies to linlin too
- People don't think she used awakening because it wasn't explicitly said she used it
- Kid and law's victory also used their epithets
- There was also a line about her getting sent to hell
- They both even had lines saying that theyll take kid and luffy's final attacks head on and survive
If kaido has to get back up because so and so big mom probably should too with most of the reasons applying to both
If all those reasons dont matter and its mainly just because kaido is an/or at least will become awakened zoan with endless endurance and stamina unable to be defeated unless he's kill then...
Luffy is also an awakened zoan and the same would also apply to him
Neither luffy, kaido, or linlin really have more of a reason to get up again and keep on fighting that only applies to 1 of them only
The reasoning and logic behind why 1 should get up pretty much applies to them all
