Luffy is weak to blades and other sharp objects.....
In their gag whiskey peak fight Zoro was afraid that Luffy was going to kill him as he crushed concrete with his fists casually.
In Oda's manga there are no after effects or scars from fighting Zoro to Mr 1, Kaku, Pica or many we could list, even fodder, so there goes the 1 sided muh lethality argument.
Oda doesn't show the realistic after effects of being exploded, shocked by millions of volts of electricity, punched by city busting fists, slashed by town slashing strikes etc.
