As far as the science being settled, once it was 'settled' science that the Sun circled the Earth. I suspect that there'll be more scientific data collection surrounding COVID, which may, or may not, invalidate previous assumptions.
My mentioning the adulting is that each adult needs to assess their risk exposure for themselves. There's little need for government to take those decisions away from those being responsible. So in Michigan, the EO came out, that all restaurants will have to collect contact information from all their dine-in patrons.
There have been a number of times where a government has demanded of its citizens to report on other citizens, and it has never turned out well for those citizens.
Many here in Michigan are of the same mind, either refusing to dine-in or providing false information. The result is just yet more pressure on restaurants already under pressure, leading to more failing and going bankrupt. Each of those restaurants needs to be considered as a small business, so the impact on small businesses is pretty clear.
There's a balance that needs to be struck, btu doesn't appear to be being stuck very well very often. Pretty sure that a close examination of the COVID data collected would lead to making some balanced decisions as to which public policies are effective and which are not, and do so keeping the economic impact in mind as well.
Not an easy proposition, to be sure, but needs to be done none the less. How many Governors are actually going through such a decision making process? No one seems to really know, as all we really have to go on are the EOs which are issued.
