But even if you were right about that, Article 50 was invoked and no insta-recession occurred.
Regardless of how you try and slice it the consensus of economists was wrong, 100% and completely wrong. There is no way to deny it.
The other elements of the forecast are coming
Wrong, totally wrong. Go read the Treasury's actual forecast:
https://www.gov.uk/government/news/britain-to-enter-recessio...
New Treasury analysis shows a vote to leave the EU would tip Britain’s economy into a year-long recession.
Speaking at B&Q in Eastleigh, Hampshire, the Prime Minister and Chancellor set out the Treasury’s analysis of the impact on the nation’s economy over the immediate period of two years following a vote to leave.
Do you see that - vote to leave. Very clear. There was a vote to leave. Their predictions did not come true. My point remains.
The other elements of the forecast are coming, they're just following on a time lag because they're dependent on choices getting locked in. The not so funny thing about Brexit is that it's like a game of chicken: the market doesn't believe Britain will choose drive off the cliff edge, so it hasn't priced in the damage; but that lack of pricing information makes it more likely Britain will drive off the edge.
It's one situation where markets might ironically be ill-suited to judge because of feedback effects. The worse the outcome, the less likely the market is to believe it, which sustains the delusion that it won't be bad.
