Yes, that's called life, we will never reduce death to zero, we will not even really reduce the total amount, 100% of people on earth now without exception will die and there is nothing whatsoever we can do about it. We can only look at preventing PREMATURE death. If Covid is the infection that finishes off someone who is very elderly and unhealthy already it is not nearly as large of a cause for concern than when an otherwise healthy teenager is killed by a new type of infection. Covid still kills a large number of people, much like flu, and bacterial pneumonia, and heart disease. It is however no longer a major factor in EXCESS deaths, is, causes of deaths that are disproportionately and significantly reducing the average age and health of the human population. Saying, some death is acceptable is an incredibly obvious fact of life when you think about it, it's pointless and futile to try to prevent all deaths.

Look at this way, "reducing death" does not mean making some people not die, that's impossible. "Reducing death" means increasing the average age of the population and reducing the likelihood of people dying while they're young.
