How is that different from requiring vaccines for public school, a license to drive a car or fly a plane, or even a safety course and hunting license to hunt? Most of the things that are benefits of citizenship that don’t require any voluntary steps are true “public goods”, like national defense or the societal benefits of education, etc.
