You seem to be very concerned about encroaching authoritarian tendencies. That's a scary word!
How do you view these measures as different from say, speed limits? In both cases the gvt is placing restrictions because it believes it'll decrease the amount of deaths overall. Calling it 'authoritarian' is alarmist and/or sensationalist. But providing good restrictions is one of the core responsibilities of government.
You're making the case that the tradeoff in restrictions is no longer worth it. I think preventing deaths should be the primary goal. It's a very straightforward goal and, I should hope, something that inherently has value for everyone. I also think you're endorsing a system where people (i.e. you?) gets to decide how many people is "OK" to die, and that makes me uncomfortable. Who gets to decide? Why is it you? If you don't belong to one of those vulnerable groups, I'm sure that's a coincidence, right?
But anyway for the sake of argument I'll hear you out. How do you quantify "economic misery"? Is there some kind of scale or measurement system you know about that can help here? I'm just not sure what we're even measuring here, besides vague feelings.
Finally, is it at all possible that you don't care at all about good tradeoffs, but selfishly you just want things to reopen for your own personal benefit? I'm sure there are a LOT of folks out there who are arguing in bad faith about tradeoffs etc when in reality they just wanna get back to the Olive Garden and go back to their own normal lives. That's why you're gonna meet with pushback with these kinds of proposals. But you can dress it up as 'omg authoritarianism!!' if you want to
