Let's run a simple simulation, shall we? One valid for the Western World in a general sense.
1. You (with this meaning "a general guy") open shop again (let's say it is a shop for simplicity). You are infected but asymptomatic. After a few days a percentage of your customers fall ill. Some tracking is done and the cluster is centered around your shop. You lose all your customers, you have to close shop and, according to the laws of your country, possibly become target of a score of lawsuits (God forbids that a customer's elderly in-laws got the virus via you). In any case, your activity is, "de facto", wiped out.
2. But wait, it gets better! You are not a carrier and everything is fine. But your neighbour is. Some of his/her customers get infected and, since they are doing a shopping round, they come to you next. Soon or later you get infected. Go to 1.
3. Amazingly enough, it gets even more better! After a while people start to realise how all this "we want our liberties back!!" brouhaha is creating hot spots in shopping areas - not somewhere you want to be. People stop shopping again, discover that the new freedom cry is "Give me liberty AND death!", and all economic activity returns back to zero - but with more people infected (and an higher strain on the healthcare infrastructure, as intelligently noted).
4. A nice ribbon to tie it all. Next time you declare how "The Coronavirus emergency is over, no really this time it is, we want our economy back!!!1 (sic)" people will be much more wary and the economy restarts in fits and coughs because (to use an Italian idiomatic form) you burned your word. And this if mortar and brick business still exists and Amazon hasn't bought the World.
Simulation ended.
Do you want to risk this? (because, admittedly, this is not a given - only a model of what could happen if the coin drops with the wrong face up) Maybe you don't agree with this simulation in the first place? Fine. Break the model. We are in a wargaming forum and this is a wargame of sorts: it should be fun! Just show me where it is wrong. The rest it hot air.
Neither European countries or the USA can afford to stay in lockdown until we have a vaccine or even 'universal' testing. So at some point we are going to have to get used to a situation where we may indeed be asymptomatic carriers but have started living our lives more normally because that is what the situation demands. It's about managing risks.
I don't think anybody here is arguing that we should now just 'go back to normal'. Similarly I think most people appreciate that we can't just carry on like this indefinitely. There may be differences of opinion in terms of the extent of 'normal' that we will be returning to and how long that will last - but that is because at the moment we are dealing with a massive information deficit because nobody really knows how many people have actually been infected. If it is a high proportion we might find ourselves able to go back to 'normal' quicker than expected. If it a low proportion and closer to the reported cases then we probably won't be able to go back to normal till a vaccine is ready. In that situation the challenge is to find the right balance between full lockdowns and full normality.
