Well, I believe that those choices affect the individual person, while Covid-19 antivaxxer actions affect Doctors, Nurses, EMT's, Hospital Staff, hotels, restaurants and I will go so far as to say the entire economy. As for Smoking, the tobacco companies should be held responsible, as for Cancer, many causes. My father died after smoking 5 packs of Camels/unfiltered cigarettes for 70 some odd years. Wound up not getting treated for Crohn's disease and dying from malnutrition, he also worked with asbestos.
So, no vaccine to help society, no insurance help. Same as in US as hurt on job while on drugs. Reap what you sow.
