Is the State a Right to Exclude Non Members?

The right to exclude is one of the rights that states are able to claim with impunity, says David Frum. He asks: by what right can the state make those kinds of decisions about you? And why do we think that that's part of the very concept of the state? 'In previous times, states have claimed other rights that we no longer consider to be part of theVery concept of the State,' he adds.
