> to be blunt: this is your misunderstanding
Ironically, you seem to have misunderstood me, because:
> fundamentally leaving the currency/monetary union and leaving the economic/political union are completely different things, so obviously they would have different outcomes
Is something I’m aware of and I wasn’t contradicting.
I was saying potential negative consequences specifically of Brexit were near-simultaneously used by the same person both were not going to happen at all and yet simultaneously that they were a reason the EU would give the UK a good deal.
In one case, the pause between these two claims being made by the same person was literally only just long enough for me to say “no” without actually justifying why I was disagreeing with him. So please, don’t just say I’m misunderstanding.
And that makes me think that in a parallel world where the UK has been in the Euro but still voted to leave the EU, the government may well have dismissed any and all concerns about the economic consequences, left, and then blamed all the harm that did happen on “remoaners” and “saboteurs” and “the jealous EU”, just like they did for the much milder difficulties they faced in the real world.
> it is politically impossible, especially when the EU's position is that "the Euro and the EU are linked: leaving one means leaving the other"
First, “Politically impossible” doesn’t seem to be in the vocabulary of current UK politicians right now.
Second, I get the impression many of the louder Leave campaigners hated both the currency and the EU, so I don’t actually see how your claims are evidence makes it more politically channeling in the UK than Brexit was all by itself. Economically more challenging, sure (though you’ve still not convinced me it would have been impossible). Politically more challenging? I don’t see it.
