I am not hugh fan of federal mandates. There are many things that feds should be doing, but on the substance of your argument:
VAERS canard is totally incongruent with all research done using controls and via historical data in multiple countries. Research discovered some complications related to myocarditis and it is well documented in terms of risk rates per age (and that risk is lower than risk of same disease from COVID).
Transmission was significantly reduced for Delta when mandates came out. You are right that the omicron seems to be transmitting more. I see only preliminary estimates that possibly transmits less but by less than Delta. So, in this sense, you are right that mandate may be less relevant.
Remaining public policy argument for vaccines is that they reduce serious hospitalization and thus stress on medical system. Paraphrasing a WSJ comment: I am a nurse for 50 years. We are all exhausted by now. Know that if you arrive here we will still take care of you, whatever your views are. But please do what you can to reduce our stress so that we can continue taking care of patients. There is also a libertarian argument – you should be free to sign a paper that you will be last in line for medical services and responsible for all medical and burial costs.
At the end, I am not sure what is our interest in discussing mandates, instead of discussing our obligations. All anti-vaccine arguments I saw here were not based on any psak, or any valid medical information, just on some website quotes, some based on gross anti-Torah notions of disregard of human life, of logic.
