> Perhaps we could create a "stupid eater law" for medicare/medicaid, forcing obese people etc to pay for their own private health insurance

That might be a good idea after we make sure that every single person has equal access to healthy foods and equal ability to afford healthier options. Maybe we could also ban companies from adding HFCS to everything, ban advertising of any unhealthy foods, fine people for not wearing masks or vaccinating their babies, and police what people are allowed to have in their refrigerators so we can punish anyone who has too many unhealthy foods in their home!

Or... maybe we can let doctors and scientists figure out what the best ways to combat the obesity problem are and try to find ways to help people instead of punishing them while in the meantime making sure everyone has access to the care that they need. If we had universal healthcare the costs for your family would the same as everyone else no matter if you or the next person drinks, or smokes, or likes rock climbing, or plays sports, or drives more than x number of miles in a year, or has more than x number of sexual partners, or doesn't exercise at least x number of hours a day and nobody would have to go around spying on everybody to make sure they aren't doing anything that might raise someone else's costs "or else".
