At this point it's clear that the most dangerous aspect of this disease is the risk of overwhelmed healthcare systems, which makes every one of us part of the "vulnerable population" regardless of our current physical conditions. When (or if) our healthcare systems adjust to this threat enough to be reasonably robust in the face of outbreaks, and to no longer be centers of infection, then lockdowns and strict distancing measures can no longer be justified simply to save lives. Nobody genuinely disagrees with this, and the reason you know this is that nobody is advocating for lockdowns and strict distancing to save lives from other widespread infectious diseases. In other words, lockdowns and strict distancing would undoubtedly save millions of lives every year from the multitude of infectious diseases we already live with, but nobody serious has ever suggested we sacrifice our economy to fight them in this way.
