So if he and Banner are buddy-buddy he would be so against sending him off, therefore being against registering the heroes? Making Cap take Tony's spot of being known? Just spitballing with my limited knowledge, someone hop in please.
Banner never got the chance to choose sides about registration. The Illuminati just arbitrarily deemed that he was a menace to earth, and decided the best thing to do was just kick him off the planet. (Even though they all knew damn well he could find his way home easily enough, as he had many times before.)
