While I agree with most of your points, Corinna, food being rationed in WW2 actually meant there was enough food for everybody. Even for people who had never experienced having enough before. It was boring and dull, but there was enough.
The panic-buying we are seeing now means that food is actually running out in places, that there are people who may not get what they need.
Families are losing their jobs over the corona and being evicted because of it and unlike WW2 the government does not seem to plan to do anything about that. People on casual or zero contracts simply won't get paid.
People are stealing from foodbanks.
So while most people will be more comfortably off than they would have been in WW2, there will be others who are actually starving. That does not seem to have happened in WW2, and employment was at record heights.
And no doubt as the weeks go on, more fathers (and mothers, and siblings, and grandparents) will disappear into hospitals and never be seen again. Or have to die at home because there will not be the capacity to get them into an ambulance.
One thing about the war was that you had some warning about the bombs. There was a chance of getting to a shelter. With a virus there is no warning: you never know when a relative returning from the shops or from their shift at the hospital will be bringing it back.
(And people will have to go to the shops; they quite clearly do not have the capacity to deliver that they would need.)
Comparisons with previous epidemics show that this fear of the hidden enemy does have a traumatising effect. The Spanish flu did, the cholera did, typhoid did, the smallpox did, the plague did. Perhaps people should have been more resilient- but they weren't.
