You're thinking this through far too carefully. You do realize, of course, that this is the Politics forum, right?Well I can only provide my personal perspective.
Germany is serving as a good example of the right way to pursue re-opening. Germany has used wide-scale testing and contact tracing to drive the effective R0 rate down towards 0.7; the intent is to have more people recovered each day than infected. In fact this is one of their key criteria for pursuing the "next stage" of re-opening.
Most medical experts have recommended that "stay at home" remain in place for 60 days before a staged re-opening is pursued with one of the entry criteria being that wide-scale testing and contact tracing is available.
I am fine with North Carolina keeping "stay at home" in place until the end of May then starting with a staged re-opening. Surveys from local media show that the majority of the population in North Carolina support this timeline.
I have not taken any money from the government; I do not qualify. All the members of my family are still employed at full salary.
From a rate of infection criteria; I would consider things safe as can be expected for start re-opening when the effective infection rate (R0) is driven to 0.7 by wide-scale testing and contact tracing. Following the example of Germany.
=====================
As a side note; I believe that the government providing $1200 to nearly all people including all of those who have not been impacted whatsoever financially is absurd. It is costing the U.S. approx $250 Billion.
We should have put this money into supporting people who are unemployed or have reduced pay/hours due to COVID-19. These are the people who need the financial support to pay their bills. I know we added $600 weekly etc. We should consider an approach to similar countries where we provide the unemployed with 80% or more of their salaries until they have jobs again when we "open for business".
