The logical extension of your statement is "don't work, go die." Is that really a sentiment we want as the basis of health care policy? For someone with such a highly developed sense of right and wrong with regard  to women's health care you sure have set the morality bar low here.
Fact is, taxpayers are already indirectly covering the cost of healthcare for the uninsured when they come to the ER for treatment. We just cover those costs in the most expensive and inefficient way possible. Subsidizing coverage for those who can't afford it increases efficiency and preventive care and lowers costs.
What's the alternative? Either we leave things as they are, people will seek treatment at the ED and costs continue to skyrocket or we buy them insurance to access care. I'm sure Richard is going to say the ED should dump them to die on the street if they can't pay upfront, but as a society we cannot afford such dystopian solutions.
