Which is what? Are you asking me now to divluge my personal preference, a viewpoint that in my opinion has no basis on the debate regarding the referendum itself? That will come after the nation has decided and we can all debate what direction the UK should take next.
It seems to me that what you want to do is drag me into a debate about how my choice would be 'wrong', and once I tell you which scenario i'd prefer to see the UK follow, I can already sense you'll wish to debate on how 'wrong' it is in order to stifle the debate; not because it is in any way illogical or unrealistic, but because you yourself personally disagree with that action. All you need to know is that my preferred action for this country to undertake in the wake of an exit from the EU may nor may not be one you have listed. My choice is my choice and you don't need to know it unless you wish to give your own choice first, given that you're placed in the scenario that the leave campaign actually succeeded, so that I can have an understanding as to the type of debate we might have. In other words, if you yourself do not agree with any of these scenarios you listed or how they could work to the UK's benefit, it's pointless asking me to choose one of them, isn't it.
