You may be right, though (and I say this as an ardent remainer), we’ve been very good at catastrophising and describing the worst timeline already. I still believe it will be bad, and Covid-19 is unlikely to help.
What I think is beyond question is that all the problems caused by Brexit will now be conveniently assigned to Covid-19 by those in charge, and when the halcyon future previously described by the brexiters fails to materialise, they have a convenient excuse to take no accountability (which has been the MO since the start).
