Absolutely right - Here there is literally an issue of life and death for citizens of this country and they get caught up in some bizarre abstractions instead of trying to fix the problem.
Fixing the problem is going to require addressing the obesity epidemic in this country. The USA has the highest obesity rate in the world, and it is expected to get worse in the future.
Why should I have to pay for somebody's health insurance when they refuse to maintain a healthy weight, exercise, or quit smoking? If you are going to demand that people work together on lowering the cost of health care, then why can't I tell people to quit destroying their health with their bad habits? It's a two-way street. Don't reach into my wallet and expect me to demand nothing in return.
Why should I have to pay for the costs of motorcycle accidents when I don't ride?
Why should I have to pay for the costs of eye injuries to welders, when I am not a welder?
Why should I have to pay for the costs of silicosis when I am not a miner?
Why should I have to pay for the costs of people with type 1 diabetes when I am not genetically succeptable?
Why should I have to pay the costs of premature babies when I'm not having any more kids?
Why should I have to pay for the earthquake injuries of people in California when I chose to live in a geologically stable region?
Why should I have to pay for the many, many national parks I will never get to visit?
Why should I have to pay for the higher healthcare costs of the elderly when I am not (yet) elderly?
It is satisfying to set up one mental account for oneself and another for everybody else. It's reassuring to imagine a world where one's own virtues and healthy habits mean nothing could go wrong, and one's insurance premiums are simply charity to the undeserving. But one day we will all need the assistance of other people. Maybe you break a hip in 20 years, or develop an autoimmune disorder, or slip a disc? I know very few people who've never had a bout with some health problem - that's what insurance is for.
Now, if you're talking about huge taxes on tobacco and sugar, I think that makes sense. Candy bars and soft drinks should cost 10x as much as they do. Tobbacco should be taxed until it almost makes sense for the drug dealers to sell.
