1. You are responding to a comment that didn't talk about mandates under an article that says nothing about mandates. You are the one who brought it up.
2 and 3: In isolation you are right, we should probably take more measurements towards healthy living. But if you only bring that up as a counter point to COVID measures, you are at very best making a flawed analogy.
My point is: if there is anything feasible measures we can take for healthier living, great we should do that. But we should ALSO do something about COVID.
