What the hell do you need it for?
As a barrier to anarchists.
OK... I'm with you on that score.
I approve of the notion of state.
Where I differ with you, is in defining the responsibility of state.
I say the state's only morally legitimate responsibility, is the defense of rights, so that we are free to pursue or own improvement and industry.
You say, the state should exist to dictate our actions, so as to make us better people.
