The problem is that merely being locked down is quite unhealthy in many ways. As anecdote, I'm drinking about twice as much, not exercising at all, canceling dental cleanings, and wouldn't go into a medical setting short of something obviously life-threatening. (And indeed, many people with stroke symptoms aren't going to the ER right away, which can easily be life-changing.)
One essay I just saw made the likely-valid point that the risk here is almost entirely concentrated in the population that's 60+ (and a few younger people with unusual medical conditions).
If so, a better plan than shotgunning the entire economy for a year or two may well be to figure out how to specifically protect those who are vulnerable, and let things run their course with the rest.
In any case, if something cannot go on, it will not. No way we'll be locked down in a year, no matter what pie-in-the-sky handouts are distributed.
