I present two advantages of our current lockdown, but two disadvantages too.  I suspect the disadvantages will prove to outweigh the advantages for most of the country (i.e. not NYC).  Specifically, I cite the risk that by putting everyone in lockdown, the progress of the disease will continue to trickle.  As a result, everyone will get tired of the lockdown and get back to business.  This will put old people and those with preexisting conditions at risk, which could have been avoided had we ONLY locked down those high-risk groups.
