Is there a story or novel in which, upon attaining an age of majority, the new adults must either explicitly sign on to a formal social contract or be exiled?
It seems like the sort of thing that should have been done, but I can't think of any examples. (Several rite-of-passage novels come to mind, of course, but that's different.) It seems like obvious Prometheus Award bait...
Not quite what I'm looking for:
- Starship Troopers (service for citizenship is not mandatory, not age-linked, they won't throw you out)
- Coventry (participation in society is assumed, exile is an option for felons)
- Those Who Walk Away From Omelas (almost right, but there's no explicit social contract, just a utopia powered by evil)
- Divergent (not sure, but appears to be about cliques and conformity rather than governing rules of society)
- anything where you have to lose or win citizenship rights rather than just agreeing with them
