I don't get the "starvation" point. As far as I know, nowhere in the world does "lockdown" mean "farmers aren't allowed to tend to their fields and animals". I live in Austria, which has been in "lockdown" for almost six weeks now. The shops are full of fresh food: Both food production and distribution are working exactly as before. There are non-staple foods where production is endangered -- asparagus and strawberries, I think -- because they depend on obscenely cheap foreign labor, which will now be flown in and given special exemptions. But even without that, we wouldn't starve without asparagus and strawberries.

Could you explain what kind of lockdown model you are thinking of that would prohibit production or distribution of food?
