The bottom line is no-one knows what the impact of Brexit will be, and how things will pan out with the new deal now that we have left the EU. Likewise, the state of Scotland, the UK and the EU after the COVID dust has settled, economically and otherwise, is currently unknowable. We don't know how the UK and EU will fare in relative terms. These questions require time to answer.
We are out of the EU now and the only way to be an EU member is to start to joining process as a new state, so there is no reason for urgency in considering this and no reason not to take some time to see where the land lies first. It's likely joining as an independent state would take years as certain economic criteria need to be met first, and I can't see a bureaucratic juggernaught like the EU waiving any procedures just to stick it to Boris, especially after their experiences with Greece etc. So in all likelihood an independent Scotland would be out of both the UK and the EU for a considerable length of time, and for this reason alone we should have as much info as possible and not take a leap of faith at one of the most unstable times in decades. Indeed, while there is clearly support for independence, I believe polling suggests most people would prefer to let the dust settle before revisiting this. If the arguments for an independent Scotland are indeed strong and robust, they still will be in a few years time, so we really should give this the careful consideration that such a big decision deserves.
I do note though from Nicola Sturgeon's twitter feed as well as the anti-Brexit/pro-independence video posted (against impartiality rules) on the ScotGov account (not to mention the turn that this thread has taken) that the plan before May seems to be to milk Brexit outrage for all its worth and aggressively peddle the myth that Scotland can easily and quickly rejoin if only we vote for independence. It seems we won't get even a moment's peace before the next big constitutional argument is foisted upon us.
