This is massively revisionist. "Shutting down overnight" was pretty much the response across the nation in March 2020. This was based on the information available at the time, and as things evolved, things changed. Everything after was basically differences in how quickly things opened back up (and what things, in what order, with what restrictions). And mass support for reopening rapidly with no restrictions wasn't…
There are only a few countries that really shut down (some only regional): New Zealand, Japan, Australia and China (others?). This one graph shows how effective it was and if we'd all done that the difference would be enormous, even for the countries that did shut down. https://en.wikipedia.org/wiki/COVID-19_pandemic_by_country_a...
The "none of this was necessary" position is just ultra-revisionist and often makes arguments as if today's variant and transmission environment is the environment that was in place in March 2020. It also ignores that individuals will make their own choices to change their behavior in the face of a new threat. "Not massively damaging some sectors of the economy" was never an option.
