Fantastic! Except you can't know in advance. So, the intelligent thing to do is to be prudent until you know what you're dealing with. Otherwise, by the time you decide it's dangerous enough to do something, you've already got an uncontrollable spread on your hands.

Right. Which the general public figured out - accurately - about a month into the lockdowns.
People will self-isolate for a week or two the next time around, but it's going to have to be a very different disease before we permit ridiculous extended lockdowns again.
Being prudent doesn't mean stopping the economy in its tracks. It means appropriate planning and monitoring, with intervention as necessary. For some reason, people don't consider the cost of an unchecked epidemy, which is just as real as that of a controlled one. Except people have nothing to complain about, since they don't feel under pressure from anyone. They just feel sick...
