It's unclear whether "1" was actually possible, given the political/legal structure of the United States. Who, exactly, would be promulgating and enforcing such an order?
With competent federal coordination and incentives, all 50 states could have used their emergency powers or even legislation to implement stricter lockdowns with real enforcement.
State and local police would enforce it, again, with the proper incentives. Fire the few local yokel sheriffs refusing to enforce. They have the ability, need the willingness. If they can catch me going 70 in a 45 or avoiding my income taxes, they can catch me going to Olive Garden.
We have the political ability but not the political will.
So, it would have been possible under the hypothesis that all 50 states can agree on an incredibly controversial policy? I doubt all 50 states can agree on whether the earth is more than 10,000 years old, so this sounds like a fantasy.
