Glad we got a deal, which although a pale shadow of what we had, is in the short-term economically clearly far preferable to no-deal.
I have wondered at times, if in the long-term a no-deal might have ultimately meant a stronger economy in the mid-term future, forcing a bigger shake-up and more dynamic response (as in Germany and Japan after WWII for example, though obviously that situation of a different order of magnitude). But that's pure speculation and I certainly wouldn't want it anyway, because of the inevitable short-term suffering.
I also wonder had it not been for the pandemic and its huge economic impact, if we would indeed have left with no-deal. The pressure created for a deal was obviously far greater, and tipped the balance heavily in favour of pragmatism over rash adventurism. But then again, with ideology involved there were no guarantees ..
On the idea of Britain renegotiating some kind of re-entry to the EU at some point, that does seem rather far off at the moment, particularly with the rise of nationalist tendencies all around. (And the sheer loss of the will to live at the mention of another EU referendum ..
