Secondly you are of course correct that "worst case/alternative scenario is forever unprovable" . However there is a useful comparison between Florida and California which adopted very different approaches to dealing with Covid but gave surprisingly similar results.
The Florida versus California argument is often touted but not valid. People who quote these figures are conveniently cherry picking outliers that prove their hypothesis (e.g., there are 52 states, and many example of those with strong restrictions that did well, and those with less restrictions that did badly).
The Florida population is not exchangeable with California, which means you cannot make direct comparisons about deaths without trying to control for additional factors.
These include the fact the Cali has a much higher population density, higher proportion of ethnic minorities, higher rates of poverty, and lower proportions of individuals who are retired (and are therefore able to minimise contact with others) when compared with Florida. All these confounders are confirmed risk factors for worse COVID outcomes.
