No, this is also opinion, and not even well informed opinion. We have never achieved widespread, lasting herd immunity from any human infectious disease in history without a vaccine. Before the measles and mumps vaccine, the closest we got were very localized, temporary herd immunity from those diseases. But it was never lasting, and it resulted in morbidity and mortality that would be unacceptable today. Allowing the excess, preventable death of several million human beings is not a "viable option".
And the other side of the argument is not "even 1 virus death is too much" and you know it.
