The fact that the virus (directly) killed 100K people doesn't tell you much of anything about the quality of our response. It ignores two crucial questions: (1) How many people were
indirectly killed? And (2) How much better could we have done in terms of
total damage with an available alternative?
The answer to (1) is starting to look like "a lot". And most tragically, it could be that a large number of those were due to well-intended actions like locking down.
It's within the realm of possibility that the right thing to do was pretty much "nothing". As in, the basic health procedures specified for flu season, etc.
Reams of papers and probably shelves of books will be written studying this, so perhaps eventually we'll have some idea.
In any case, as others have pointed out, the protests have pretty much wiped out the idea of locking down. The economic costs (think: people who will go broke and die from it) even more so.
