They were created and imposed by political entities. What other sorts of constructs would they be? Is this Captain Obvious day, and no one told me?
Sure, just like THE SCIENCE (a non-political human construct) fueled the political policies leading to mandatory smallpox vaccination, fluoridated water, underground sewers, etc.
The mandates/emergency states may or may not end end on March 1, as THE SCIENCE responds to changing conditions in the world. I'm hopeful there, it would be nice to host my game day again. If not THE SCIENCE, what should have been driving public policy instead? THE PROFITS? THE PROPHETS? THE LOGICS? What's your alternative source for reliable policy during a pandemic?
