Most likely she is deciding between food, shelter, clothing, electricity, bus fare, and health insurance. Out of those items, if anything must be removed to make ends meet it obviously must be health insurance.
I wonder what will happen to her when she must buy insurance or pay a fine. Which of the other items will she give up? Obviously not bus fare, she loses her job without it. Probably food, and keeping her house VERY hot and VERY cold in the summer and winter, respectively. This will make her sick, but then she gets to use the health insurance...
True, something would have to give to afford it. But let's look at those other essential commodities you mentioned. If you were unable to afford a bus ride, would the bus service still let you on? If you were hungry but unable to afford food, would a grocery store let you continue to shop and take food if you never paid for it?
So, why then, do uninsured people feel it's A-okay to use medical services without paying any bills? It's an ugly thing to say, but if you can't afford medical coverage, and the American people are not willing to pay taxes for public health services, then you should be shit out of luck.
Instead, there is this ass-backwards subsidization where people get sick and a hospital immediately turns into a charity. The hospital can't collect money from people that don't have any
...which causes medical services for those who can pay to be even more expensive
...which makes health insurance that much more important, and more expensive
...which makes it harder for people to afford insurance
...which leads to more people using the ER who can't pay for it
...which leads to more ass-backwards subsidization
