The other thing that strikes me more and more about this is: what determines R0? The figure we use for London is about 2.5. But it must be a function of how people interact in a given community, rather than some intrinsic property of the virus. I can quite easily imagine it may be only 1.5 for a spread-out community that des not uses public transport and does not do much office work. One issue must be whether we need the same lockdown conditions everywhere. Perhaps we need them more in the densely populated cities than we do in rural areas.I think it's too early to open up in most places but I like the idea of thinking about how you could widen the businesses that could be opened but not the ones that everyone is talking about...getting your haircut, etc.
Some people might think it's more important to get a haircut than to open up the local garden center but that's not the point. You can't stay away from people if you are cutting their hair.
People are home with nothing to do. They could go to a garden center, buy a few plants to come home and plant (as an example). You can have spacing by the cashier just like in the grocery store. You could limit the number of people in the garden center at any one time.
I'm sure there are other businesses out there like that when it is time to open things up a bit more if for no other reason than to limit the economic suffering of many lower paid employees and to reduce the sense of panic in the population as a whole. There is going to be a heavy price to pay by completely shutting down the economy for too long.
There are some states with relatively low numbers of people with the virus. Of course those numbers can increase rapidly but they don't have to if the businesses that open up initially are low contact and low density businesses....and that's not bars, restaurants and hair salons.
On the other hand, if one were to introduce differential degrees of control, I can see it might be thought lacking in solidarity if it were only the cities that were locked down, while suburbia and rural areas only carried out weaker social distancing measures. One could imagine a lot of resentment from those in the cities, thinking visitors from outside might reintroduce the plague to them, or that the rural areas were somehow getting a free ride on the back of their own misery. Even more explosively, in the US context, the cities tend to be Democrat and the rural areas Republican. So there would be huge scope for perverted campaigning, in which Republicans, say, might present the plight of the cities as the fault of their political opponents, rather than the epidemiological fact of closer contact. And then the Republicans might resent the Federal handouts that would be necessary for the cities, to get them through the epidemic. It could make US politics even more of a snake pit than it is already.
But it looks as if that may be the way the US goes, gradually, as some areas ease up and others don't.
Good luck!
