Isn't is plausible, if not expected, that countries with different industries and economic structures would do differently with the exact same kind of lockdown plan?

That is, a country that has a large WFH-capable population would feel less economic pain than another otherwise similar country?

And thus, maybe a swift and harsh lockdown is the best move for one country, but the cons for another would outweigh the pros? That is another country would enter an economic decline that overall costs more lives than would have been saved?

We don't know the answers to these questions, but I think we shouldn't dismiss these considerations.
