It would. But the correct choice is not obvious anymore, don't you see? Both worst-case outcomes lead to millions of deaths, and you're not able to prove which is more likely.
I don't buy that. Judging from the actions of governments around the world, many of which made drastic course corrections based on recent findings, the consensus is that the risk of millions of deaths due to underreaction is far greater than the risk of millions of deaths due to overreaction. Of course, it will be important to continuously reassess the situation and make course corrections in either direction based on new findings. In the meantime, governments should do everything they can to mitigate financial hardship and keep the economy alive. Unfortunately, there is no way out of this that won't cause significant pain.
