I'll end with this, from a behavioral science point of view, I dont think not having a time frame most can plan around, even if just figuring out how to deal with it mentally, is practical. They are eventually going to give up, much like with a diet that has no end date. True, it may not be the best thing when some who really need to be on that diet goes off it, but most do and in this case most will as well, no matter how much we scream to the heavens not to.
Especially given the case that for the most part, the majority are not in danger of dying from this. As more and more politicians and celebrities get this and survive, this will become more evident and will make a stronger case to most that they can go outside and work, make an income instead of watching their family starve, get financially ruined, loose all they have worked for, etc.
People don't work for society. When the rubber meets the road, they work for themselves and their family. We may think different, but we have the advantage of being wealthy at the moment. As that wealth decreases though, we will become more and more like the previous poorer versions of ourselves generations ago.
We need to start thinking about how we will protect the elderly and sick when this breaks, and break it will. We need a more practical plan for those most vulnerable then "everyone just stay inside damn it!"
