people dying everywhere (which, with a hopeful 2% letality is still very likely) will also heavily disturb the peace as well as the economy. As long as we are not sure about basic things like that, I'm quite for a lockdown, because a 7% letality is still not off the table (with happy things like reinfection) - and this is basically about double the loss of life of WW2 (which at least had a clear winner, being able to play out its game).
So: how are you sure that the parameters of the pandemic are something, the system can handle? Is there any precedent for that? What reason is there, that our society (that's the people, making up this system) can't overcome this crisis with something different?
