I live in a suburb of a large city in Canada. We've had virtually no cases in our area even if we are 30 min to downtown that has had a fair share of Covid. Do people stay exactly in their area all the time? No, but that does not still mean that the transmission is a problem in those areas. They can design circles of risk around downtown, include or exclude what they want but closing businesses across the whole state because of just certain areas will seem very unfair to some people.
Yeah, but, the pandemic doesn't care about fair. Pretty much everyone in the world had their lives affected. "Fair" isn't really an issue right now, we're still trying to preserve life. Areas without transmission are only that way for a while. We are seeing that now. States that did not have impact when WA, NY and CA did seemed to think this is no problem, yet, now have their own big and growing problem. Our small cities with an interstate exit didn't have to wait long to get cases.
Shutting down stuff over here and not over there only creates statewide whack-a-mole, as people go over this county border for that, back to home county, over here for that... the more people that are moving around that don't have to be moving around (not essential workers), the less potential infectees, and way fewer vectors walking around.
which residents are going to be up to the minute on these circles drawn around downtown? Who would manage that? Let alone, explain it to the residents around all those circles, why they can't do this or that, yet Joe across the street, outside of the circle, has no restrictions... nah, has to be simpler. trying to get precision on it would only work if everybody stayed right where they are....
