 Other major theories offered as solutions to the boundary problem face similar problems. For example, the coercion theory holds that anyone subject to coercion from a political body ought to have a say (López-Guerra 2005). But this principle might be also be seen as over-inclusive (Song 2009), as it would require that resident aliens, tourists, or even enemy combatants be granted a right to vote, as they are also subject to a state’s coercive power. Further, who will be coerced depends on the outcome of a decision. If a state decides to impose some laws, it will coerce certain people, and if the state declines to impose those laws, then it will not. If we try to overcome this by saying anyone potentially subject to a given state’s coercive power ought to have a say, then this seems to imply that almost everyone worldwide should have a say in most states’ major decisions.
