"it's difficult to leave so why bother" - It's difficult to beat with a whisk than an electrical blender so why bother. - It's difficult to play field sports with half a team so why bother. - It's difficult to cut off your nose to spite your face so why bother. At this time, this is how this argument sounds to me. The EU is an emergent phenomena. The natural course for a collection of neighbour states that wish to have peace and free trade. The UK still wants to have peace and free trade for sure, but has decided to construct an entirely different artifice through which to pursue these goals, quite apart from the states with whom she wants to continue to have peace and free trade!
