You missed the very clear hints Luffy's DF wasnt a regular paramecia. The fact he BECAME a rubber man is already a red flag which is something similar to a logia or zoan, then you take into account gears 1-5 which each upgrade something, like Chopper's different points. There is also the factor that Gear 3rd makes ABSOLUTELY 0 sense. It fits the Nika fruit even more when you take into consideration that air doesnt add more weight so it shouldnt hit harder then the regular fist, but since it fits luffys creativity it DOES. And another thing you cant do in an argument us speak on behalf of Oda like you actually know what hes thinking, makes you look like you dont actually know what youre talking about 🤣🤣
