I suppose you are referring to having R0 below zero. Now then the question becomes what kind of measures are necessary to keep it there and if those measures are feasible long-term. If those measures are not feasible long term (this seems to be the case), that means they R0 can be held below zero only briefly. In other words, the spread of the virus is only slowed down (or even reversed briefly, with R0 < 0) and delayed, and in essence the most deaths are simply delayed and not saved. While the deaths from the quarantine measures itself doesn't seem to ever get accounted for. And that is the problem - those quarantine measure/economic damage deaths doesn't ever seem to be put into equation as if they don't exist or are negligible. Which makes me question if quarantine does net-benefit or does more harm in log term when all the externalities and knock on effects are actually accounted for. Or am I missing something?
