Are you suggesting that letting covid run loose is OK because society's overall death rate will be the same as it was 15 years ago?
That argument has severe moral and ethical problems.
I also think you're underestimating the impact of letting the virus run loose. Countries with very poor pandemic management have seen large increases in deaths. For example, Peru's death rate this year is 156% of what it was last year. And that is only half of the year, and summer. See https://www.ft.com/content/a2901ce8-5eb7-4633-b89c-cbdf5b386...
