Indeed it would, but a deal "under any circumstances" doesn't lead to a good deal.
We would not be the only ones to be economically hit by a no deal, so we have to be willing to use that to get to an amicable arrangement.
But there comes the crunch, I don't mind the economic hit. I was told lots of times that it would be horrendously detrimental, it hasn't been, and soon we'll get our independence back.
