Marcus, your argument falls apart because you can apply the same argument against universal medical care.

Unless you meant to imply we should scrap universal medical care.

A great many health problems can be avoided by proper preventive care of one's self:
- do not drink alcohol in excess, do not get alcoholic liver and brain diseases
- do not smoke, do not get multiple lung diseases 
- do not skip drugstore birth control, do not get unwanted pregnancy and abortion
- do not take up risky hobbies outdoors, do not need orthopedic trauma surgery 
- do not skip using sunscreen and shade, do not get malignant skin cancer

Sorry, your argument is weak.
