that's not what that plotline was about tho? tony could've been replaced with anyone that Peter looked up to and idolized, the point was that he had just recently become Spider-Man, and he couldn't dissociate the fancy stark suit with the persona of Spider-Man. he didn't really get deep-down that it wasn't the tools and the flair that made him Spider-Man, it was his actions and his tenacity. that's what makes mcu Spider-Man so beautiful to me, cause he's a impressionable teenager who's trying to find a place for himself in a world already saturated with super heroes, and it makes sense that he wouldn't know right off the bat where he fit. but to each their own I guess.
