On what is based a personal choice? It's based on some information as well - so by trusting a Facebook expert we choose to not trust a medical expert. Choices? Yes. But while some of them are damaging to the feeling of liberty, others are damaging for both the public and personal health, when we are replacing experience with a loud mouth, or substituting medicine with philosophy. And while the state can do only so much for the personal health, we expect from a state to take care of the public health - thus the tyranny of personal choice is in a wrong place in a working society.
