What is the value of a human life in covid decisions?

I realize this question will shock many decent human beings. In fact, my wife gets on my case all the time for even thinking in terms of calculating the value of a life.

However, let us be realistic. If our ONLY purpose in life was to preserve human life at all costs, we may do some or all of the following:
1. Reduce speed limits.
2. Cancel FDA approval of most chemical substances, including artificial sweeteners.
3. Quarantine ANYBODY with flu-like symptoms; not because it may be covid, but because flu kills just as well.
4. Ban beef.
5. Ban flying.

Since we don’t, we implicitly perform a mental calculation and determine the risks can be justified.

The same calculus has to be applied to our recommendations for dealing with covid-19. We can estimate the economic impact of a lockdown and can estimate the number of lives that might be saved. Then it becomes simple arithmetic.

Do you think such a rational approach can be utilized?
