Difference between doing something and doing almost nothing is still 10x dead/disabled. And Sweden basically hit their best case scenario.
Most of Europe started reopening in areas with very few new cases. I don't see why not.
Also likely with the next run, if that comes, we can get away without mass quarantine.
The quarantine wasn't because of how lethal/contagious covid-19 turned out to be. It was for the bottom 10% of possible scenarios.
