Revolutions unleash euphoria because they create tangible images of change and inaugurate, at least in the fevered minds of their supporters, a new epoch. Brexit can’t do either of these things. The problem with a revolt against imaginary oppression is that you end up with imaginary freedom. How do you actually show that the yoke of Brussels has been lifted? You can’t bring prawn cocktail-flavoured crisps back into the shops, or release stout British fishermen from the humiliation of having to wear hair nets at work on the high seas, or unban donkey rides on beaches, or right any of the other great wrongs that fuelled anti-EU sentiment – because all of it was make-believe.
