Abstract
If states have the moral authority to decide their memberships by denying citizenship, I argue that they may also strip citizenship, from law-abiding members, for the same reasons. The only real difference is that when states revoke citizenship they may need to compensate people for their prior contributions, but that is not unlike what frequently occurs in divorce. Once just termination rules are established, stripping citizenship could become, like divorce, an everyday event. Partly because of this implication, we should reject the membership authority of states.
