There's definitely not a universal acceptance of Covid lockdowns, in fact in the US and even in parts of Europe, there is a growing resistance to lockdowns. The Covid lockdowns - at least initially - seemed like a reasonable reaction (for some people, no me) due to the concerns over a little known disease that was hyped as way more deadly than it ultimately ended up being. Regarding climate lockdowns? With the pushback already heating up related to Covid lockdowns, my opinion is, you try to add an even more nebulous and unprovable reason for a lockdown on top of the bullshit we've already been dealing with and you will have reached the "find out" portion of the evening's entertainment.
