I haven't had a chance to hear the report - my audio playback isn't working - but a couple of thoughts.
I don't think any responsible person is suggesting that the lock-downs continue indefinitely, and I say that being in an endangered cohort, as Jim is. We know that won't work forever, and even if it did, the economic repercussions will be disastrous and politically unacceptable. But that's not the only point. This has become binary choice - stay home, or go out and behave the way you were acting on January 1st.
Setting aside the issues surrounding the original crisis response, there are practical steps we can take as we emerge from the cocoon. First, masks. Wearing masks has become politicized beyond belief, but there are strong indications that masks protect the wearer in some measure, and also protect those who come in contact with the wearer. For some people, not wearing a mask has somehow become the rough equivalent of flying the flag. That's BS.
That leads to the next point, which is social distancing. People are ignoring it. Take a look at the line of folks waiting to enter a NASCAR event in North Carolina, where some tracks are operating under relaxation of the lock-down. There isn't 6 feet between the front of the line and the back. Beach scenes - people are back invading one another's space.
Americans have an independent streak that works wonders in many respects, but here, where there is a clear public health mandate, they won't comply. That means when I go out, wearing a mask, I'm constantly encountering unmasked people who flaunt their independence by invading my space, and staying there, which enhances risk. When they say 'I have a right [to do so-and-so]'. you want to send them back to read John Stuart Mill (or Oliver Wendell Holmes, if you prefer) and tell them it ends where my nose begins. All freedom in a modern society needs some limit. I'm not sure where you come down on that.
(The Canadian comparison is useful but limited. Culturally, Canadians seem much more willing than Americans to comply with governmental mandates, although that varies from province to province.)
So, I take your broader point that we must curtail the economic damage and accept some measure of risk, but for me at least, the real issue is that many people treat an elimination or curtailing of the isolation as a 'get out of jail' card that allows them to keep flaunting public health mandates when compliance costs them nothing except the ability to say 'I do what I want, not what I'm told to do'..
If you haven't already read it, you might enjoy 'The Great Influenza' by John Barry. It was written before the current pandemic, but it could have as well been written yesterday, that's how prescient his writing is.
