Where are you getting a 2% death rate or expectancy that 100% of the population will be infected?

The numbers I've seen are 0.66% death rate, with an average remaining life expectancy of about 10 years among those who die, and estimates that between 15% and 70% of the population would be infected.

70% of 0.66% of 328M is 1.5M deaths, or 15M years of life lost. That is indeed a big number.

Smoking has been estimated to reduce life expectancy by 13 years for heavy smokers. There are about 34M smokers in the US. I don't have the exact stats on number of heavy smokers and how long people smoke for, but assume that the average smoker smokes for 20 years and loses 5 years of life expectancy over that time. That's about 850,000 years of life lost _every single year_ to smoking alone.

I think the question of "would it be worth 5% of the current COVID-19 measures to stop smoking entirely for 1 year" is a valid one.

It would be if smoking was an infectious disease.

This activity smoking causes a disease.

Leaving quarantine causes a disease.

It's personal choice to do either activity and corona is the only disease where it's somehow the rest of the worlds responsibility for people making poor choices.

It's personal choice to leave quarantine but for some reason corona is the only disease where it's somehow the rest of the worlds responsibility for people making poor choices.

You act like there's an alternative. The only way out is through, it's all just delaying otherwise.
