I'm confused as to what you are arguing. The concept is just an application of statistics. Less people will die from the broad application of the vaccine vs. not, so we choose to vaccinate.
If you mean 50%+ as majority then yes. But a nonvaccinated death rate around 2-10% worldwide compared to 0.1% of the US vaccinated population getting covid to begin with, that’s a huge difference.
The case fatality rate has been quoted to be much lower than that - 2% in bad cases (health care system failure) and 0.5% in more well managed situations.
