I don't know how to solve obesity, I'm not trying to. But back to the current situation, vaccines are a practical way to help keeping health services functional. It doesn't solve other health issues, and is much less restrictive that going after smoking, eating, alcohol, under-exercised people, etc.

I'm not sure what are you suggesting. Applying all those restrictions? People are already barely accepting current restrictions. Or do you mean since we can't have all those restrictions, we must have none?
