Only one 'consequence' has ever mattered, though, sw: Getting out of the fücking EU.
Everything else is just detail. It's like a divorce. You don't get divorced knowing every negative or positive consequence of doing so. You get divorced because your relationship has reached an irrevocable point of breakdown.
Every potential difficulty of leaving the EU (and several made-up ones) was flagged up to us before the vote and yet we still voted to Leave. That is an informed decision. We wanted out regardless of the 'consequences'.
