Here in California, our governor has declared that we will do this indefinitely (!) until six criteria are met. Well, I hope they have some really concrete plans to meet them, because I haven't seen any such plans presented to the public. The absolute devastation we are doing to the livelihoods of so many is staggering. What will happen when the tax revenues run dry and the tax base has been reduced by some huge percentage? Coronavirus will still be around when that happens.
The virus is here, and will not be eradicated. Society cannot hibernate like this sustainably, certainly not until a vaccine arrives. I'm all about masks in public, social distancing rules, bans of large gatherings, and lots of resources directed to protecting vulnerable populations. But I'm afraid and convinced that the stay-at-home orders will do far far greater damage to society as a whole than the virus would/will under a more targeted mitigation scheme.
Maybe my fears are overblown because of the recent hit to my mental and physical health. My gym was declared illegal, as was access to all parks in Los Angeles, as was my ability to work in an isolated office without a needy toddler in the room.
