"Don't you think that UKIP and Rees-Mogg's so-called European Research Group would have had the time (decades...) to have well-thought-out & Researched answers to all these conundrums ?"
Is the European Research Group the elected government? Farage's UKIP had a plan but they are not the government. The remain supporting Cameron who offered the vote refused any planning on the basis that there was one 'right' answer and they will do all they can to force us to vote that way.
It is the insistence of having our cake and eat it which is the problem. Aka no brexit even though the voters support brexit and have voted for it.
