What's stopping them now? This "lockdown" we are in is just a word.... Unless Marshall law is declared and the troops are deployed... none of this is lawfully enforceable, and everything is a suggestion, guideline, or request from our leaders... I read a document that said this once.
Obviously (like I said)... things like public transportation and air travel effect those "handful of densely populated areas in each state" I was referring to... and yes... those places and those methods of travel need to be way more prudent with their choices to re-open, and what to re-open and when...
My point was there are hundreds of thousands of places around this country that do not have airports, public transit, nor have they been overwhelmed by this... with some common sense guidelines on sanitation, social distancing , and minimal essential travel requests... those places can re-open now.
We live in a Free Country... for anything to be enforceable, it first has to be lawful... that's just the way it is. At some point we have to give our people guidelines, best practices, and ask them to follow them... then trust them to do so... just like with everything else... especially in areas where this has not been an issue, and is far less likely to be.
