There has been a misunderstanding. I apologise, as it is my fault that you have got the wrong end of the stick. You have been labouring under the misapprehension that this whole brexit thing was an accident; the consequence of poor dialogue and badly calibrated decision making. In short, that a yes/no decision was a balance-of-probablities tactical decision seeking optimal economic outcomes. That this is a matter trade balances, calibration of welfare policies, complexity of customs arrangements, and that if the debate had better focused on these matters we’d have arrived at a more optimal decision.
It wasn’t. Rather, it is a moral strategic question of who you want to be, and whether your current path will achieve this.
