The current political class is going to be at the end of their career when the brexit takes place, since the economic repercussions will be severe, even in the most optimistic predictions a recession is expected.
I know they are going to blame all bad things from the exit on the EU, but when a year has passed that scapegoat that is no longer really present, knowing very well the whole sales pitch was "we don't need them!", it won't work.
So while i can understand your logic, to me it simply seems to be delaying the execution.

Because that would be an equally retarded mindset propelled by the brexiteers. Making you no better than dribbles or floopa.
The economic repercussions will be felt on both sides, this might even effect your line of work. Our economies have been connected ever since globalism was hailed to be the next best thing ever, a road to utopia. But this also means both sides will take losses, the EU will recover faster, individual nations will have a harder time, which is why these talks are happening with the EU as a block and not individual nations such as the UK desired, in an attempt to put nations against each other.
So no its not that simple as "let's just kick them out", not to mention it would play right in their hands of making the EU look like the "big bad wolf"
