It's worth noting that reopening early will also cause economic damage, and possibly more that not doing so would.
People dying costs money, both in the lost productivity of the dead and reduced productivity among those emotionally affected. More people will die with an early end to lockdown than would if it was maintained for another month or two.
I expect lots of grim economics research to come out of this.
The consensus among economists is that not having a lockdown would be worse for the economy than having one: http://www.igmchicago.org/surveys/policy-for-the-covid-19-cr...
The opportunity to avoid economic damage passed as soon as COVID-19 became pandemic. Ending lockdowns early will make economic harm worse.
This exact same debate played out with the 1918 Flu, and regions that took more stringent measures for longer came out better economically: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3561560
