Earlier quoted context omitted.
No, they're saying that excess deaths is a rearward looking metric that nobody had the luxury of actually having at the present time when decisions were being made. It's very easy to make decisions in retrospect when you have all the information that could be useful. It's very hard to make decisions in the present when that information doesn't exist yet.
Obviously rearward looking metrics were irrelevant and no one, including me, is suggesting otherwise. You can make policies with the goal of reducing deaths in advance of measurement, and policymakers did. The argument I am criticizing never mentions rearward metrics as a problem.
The assumption that friends and family will calmly watch a family member’s untended death from covid when ICUs are over capacity and that essential workers will continue to show up for work knowing there is no hope for care if they fall ill is unrealistic in my opinion.
