It's not like his stamina or endurance gets better with gears so is there a point in your argument?
He would still be unable to do anything against Cracker, you realize that?
Zoro alone will deal with Luffy without even going all out.
Swordsmen are Luffy's kryptonite, that's why he stays away from them.
Law alone is enough too. Kidd is Cracker v2.0, bad match-up for Luffy as well.
"You either die a hero or live long enough to see yourself become a villain."
You pointed a finger at people for matching Zoro with King and called them Zoro-tards and now you are matching him with King.
Life is full of surprises.
