Interesting thought experiment.
Imagine if the governments of the world had said, it is what it is, old people should do what they can to protect themselves everyone else keep going to work the economy is all important and we cannot shut it down and lock people up without causing huge problems down the line. We have to keep working to pay to fight climate change which is a much bigger threat.
500,000 Americans had died and someone calculated that the government has saved billions in unfunded liability like medicare and pensions. Young people pay taxes old people consume them.
Would Trads and other conservatives accuse said governments of euthanasia? Putting the economy above life?
There is nothing to compare the 500,000 deaths to other than a computer model of what would have happened if we locked down instead.
Worth considering.
