It feels to me like it's just sort of a general rebellious nature and...sort of the sense of "screw the man" that punk rock (like Green Day) is sort of based off. It's just saying "I'll do what I want, screw anyone who tells me otherwise". And so the whole thing about it being the end of the nuclear family refers to the concept they had in the 50's and early 60's about what a family was, and that now it's time to break out of the grip of that ideal and explore who we can be without trying to focus too much on what anyone else wants.
