Perhaps other people disagree with you about whether zero covid is possible?
After all, you begin by assuming that 1/3 to 2/3 of us refuse to wear masks, get vaccinated, or move social events outside. Under those assumptions, covid spreads widely. But that is not the only possible choice we have for our behavior.
A high vax rate and moderate mask/distance/outside norms are enough to drive hospitalizations near zero. Vermont is averaging one hospitalized covid patient right now. SF is around 25. Both have fewer than one covid death per day.
Now, if you want to open schools, burn your masks, and ban vaccine requirements, then you’re in Louisiana/Arkansas/Missouri territory, with around 1000 hospitalizations and 10 deaths per day.
But that is our choice. We don’t have to pick the stupid option.
