"We don't actually know anything about prevalence but it might be catastrophic" isn't the thought process that I really base my decisions on but go off bud. Don't try and use extreme outlier cases as an emotional appeal, it straight up won't work on me.

The solution is not to descend our society into complete economic collapse and massively increase mental health issues, abuse cases, financial insecurity, potential starvation, stunt our children intellectually and socially, etc. There are countless reasons why lockdown isn't a long term solution. There's also a psychological aspect that you're completely ignoring. People straight up will cease to care about lockdown measures. It happened after two months, I have no idea how you expect it to keep up into the summer and beyond. You can call it dumb and selfish if you want to, but it's reality. Focus on mitigation strategies that allow people to live their lives in some way instead of pretending that people will just willingly stay inside their homes for an extended period of time.

You also need to stop acting like lockdown is the only thing preventing this from turning into the plague. Why has sweden not descended into apocalyptic chaos? Spare me on the idea that we'll have to rebuild society if we open up too soon. This isn't the plague. Also just as a last thing, I love your thought process that the Spanish flu of 1918 is iron-clad reasoning as to why we'll have an apocalyptic second wave but the great depression is a step too far.
