Full suppression will require total shutdown for ~18 months.

Mitigation, specifically requiring the sick and elderly to self-isolate and quarantinging COIVD-19 cases and their families, will result in 2-4 million dead (depending on its effectiveness), with the situation over in 3 months.

Your post is grim, but I suspect that some countries will make the same calculation as time goes by. Here in Poland, we saw one of the first lockdowns for a European country, but the lockdown stopped at closing the border, schools, large restaurants and malls. Other shops remain open (I just went hat shopping today, for instance), people are traveling between the city and their country homes, and the feeling seems to be now that if you want to avoid infection, it is your own responsibility to stay home instead of expecting the economy to shut down.
