I had no strong feelings about staying or leaving the EU, I voted leave purely because my partner voted stay, if she voted leave I would've voted stay, because neither of us felt strongly enough about one of the other, it was essentially a way of spoiling our vote.
It might be the EU's vision but it would still make absolutely no economical sense to deny it, it wouldn't be the UK asking to return to the EU with special privileges, it would be an instance of drawing up an entirely mutual beneficial trade agreement. If you provide me with one singular economic reason why this would be a bad idea?
