Brexiety.
Sometimes you just have to say: No, that's not going to work. That's actually a bad idea. Go away and think about the realities, the obstacles, the objectives, the sustainability, the fairness, the best and the worst outcomes, then think again about what you think you want and look at the possible future scenarios caused by your decision. Brexiteers, even if you still believe in the theory, it is not playing out in practice... and we aren't even there yet. Withdraw Article 50 for all our sakes. Go back to the drawing board.
