A lot of health risks, including at least the top 6 causes of death worldwide (heart disease, stroke, lung infections, COPD, respiratory cancers, diabetes) can be substantially mitigated by personal choices such as diet and exercise

That's true, but genetics is literally the opposite: it's the one thing you definitively can't choose to change. So your argument doesn't work in the case being discussed.

If you had to pay an extra $200/mo to your insurance company because you were morbidly obese, one would expect that this would encourage a lot of people to start eating better.

One would expect that all the existing drawbacks of being morbidly obese would encourage a lot of people to start eating better. Why would this specific drawback work when others haven't?

Because spending $200/m hits you more than just the thought of future illness.

I don't support this bill, I do want this idea explored / discussed - as in, why should healthy people subsidize costs of insurance for the unhealthy? (as in, is not fair is it?)
