"...just what the brex addicts wanted: thousands more civil servants and bigger government"
IF it needs 30,000 more scribes (a big "if", hence the capitals) and assuming it costs an average of £50k per annum to employ each one, then at £1.5bn per year compared to the £10bn we lose as a result of membership, I would consider it very good value indeed. (And of course the spend will only be needed whilst our negotiations and withdrawal are in progress, not forevermore as the contributions would be).
But I'm still yawning. As with the referendum debate before the vote this is becoming extremely tiresome. People who say Brexit will never happen and those who say it should happen tomorrow are at the opposite ends of a very broad spectrum. Nobody in government or opposition (the Labour Party, that is) has suggested it will never happen. Just because it's said to be hard and just because it is said there is no plan does not mean very much. My own view is that it will happen, A50 will probably be triggered before next summer and our withdrawal will be completed a good bit before 2020. My view is, of course, pure speculation as is everybody else's.
But I've never been one to suggest that something cannot or should not be done because it is not easy or straightforward. Very often the greatest advantages are gained by doing something that is a little difficult.
