Having isolated situations where some restrictions need to be reinstated to control a surge or outbreak is very reasonable. The talking point here is always the black and white thinking of we either open everything or we are in lockdown and we’re never going in lockdown again. In the other places you listed they identified issues resulting in spread like travel to certain parts of Spain and made people quarantine when doing that. It’s a far cry from a full lockdown or even much less than the less restrictive stay at home orders we had here. So if the point is we can’t ever add back any restrictions than I disagree with that completely. Part of “living with the virus” is accepting the rise and fall of cases. In good times when they are down you open as much as is safe, when the trend turns you quickly ratchet down. That was supposed to be our plan. That was talked about at nauseam here. Instead what we got was open, ignore the consequences, deny there’s a problem until it’s too late to contain and then settle for “there’s no way to stop this virus so let’s just let it rip”.
As far as a plan B that is something that will be worked out if/when needed. Plan A is to contain the virus, get as much of the economy open as possible, keep as many people safe as possible and wait for a vaccine. We know some activities just aren’t possible and some businesses can’t be open or be open with any meaningful demand. That’s part of the process. If we get to the point where there’s no hope for a vaccine we then have to see what the state of the virus is to form a plan B. What kinds of treatments have been developed, what additional knowledge do we have and ultimately what will the new normal look like. Right now this “new normal” we talk about is a temporary normal. Without a vaccine we will need to come to terms with a true new normal. I don’t think it’s worth anyone’s time to plan that out today because there’s too many variables to contend with. I wholeheartedly reject the idea that there’s a chance a vaccine won’t work so we should just jump to plan B now. That’s just an excuse people use when they don’t want to be restricted. A little bit of self control isn’t too much to ask. Let the process play out and if we do need to switch to plan B then we’ll figure it out then, but plan B is most likely an ugly situation filled with sickness, death and years of economic depression. I pray thats not where we end up.
