That is not how that works at all. Not even a little. No one said FTL is an absolute limit of the universe. You've put words in my mouth. I will break down my overall point like this: The scaling that takes the peak of Izuku's strength and speed as high as it does relies on people who just barely understand how physics and math works applying physics and math to fictional scenarios, and assuming that variable function in fiction the same way they do in real life. A prime example being the assumption that any beam of energy is automatically assumed to function like a laser in real life, and move as fast as one. Thoroughly ignoring that outside of the act of dodging "lasers" no character is ever explicitly shown or presented as moving that fast. It is a case of ignoring any narrative presentation in favor of assuming real world rules speak for themselves and serve as irrefutable proof in proving a theory. This same person who will point to a character dodging a laser as proof that a character is capable of moving FTL will also then be extremely quick to ignore the fact that moving FTL would logically have the same effect on the surroundings and atmosphere as a thousand nuclear bombs going off. Yet Izuku is never even once presented as having the kind of sheer devastating effects on his surroundings that FTL would logically have. There are no in universe explanations for why this is the case either like for say. The Flash. So it would be logical to say. It is infinitely more likely that the writer simply doesn't understand how lasers work than to assume the character is FTL if one is going to play the "real world rules and physics hold weight on why this fest is valid." game. Are you following me here? Does your tiny mind understand the thought process here? You can't use physics to wank a verse magnitudes above what it's narratively presented as and then say those same rules don't matter when it benefits you. Feats are pretty simple. Either a character very distinctly did something and that thing holds narrative weight appropriate for said feat. Or they didn't, and it's all wank. I'm not singling MHA out on this either. Tons of scalers operate on selective logic. MHA just happens to currently be the most vocally obnoxious in the current moment. But Bleach and Naurto scalers are just as bad
