I think thats more opinion than objective ground truth, but it may have been sane in some senses. It also probably would have led to other problems. Absent a time machine, I think we're probably down to the differential stats between states and territories with and without high vaccination rates, and compulsion.
This is going to ring on for decades. Its linear optimisation, what-if big stuff, the epidemiology is going to go on and on. Surplus mortality stats are only just rolling in, worldwide.
I don't personally believe in the conspiracy side of this, what I am trying to say is I agree politically, compulsion fed it. Had I been in office, I probably would have voted for compulsion but I would have voted for compulsory return of weapons and a bunch of other laws too, so I am probably sin-binned on those grounds.
I'm not opposed to compulsion per-se. Historically, It's narrow, but (I believe) neccessary from time to time. Lots of people don't agree, thats probably the root problem here: The limits of reach in the state, and how people react to it.
