Insurance companies, by and large, make their money on the delta between the prices they charge and the costs to deliver service. If they can delivery service to a predominately healthier population, then they can deliver service for lower costs, meaning they can lower costs to be more competitive, while being able to make more profits and deliver better outcomes.
The notion that they want to drive up healthcare costs is kind of ridiculous. If that were true, they'd be rushing to sign up patients with terminal illnesses and costly pre-existing conditions, but the fact of the matter is that the government had to literally force them to for that to happen.
Here are a some links I've collected on the topic - obviously, I'm a little biased but I have yet to see any compelling case for privatised healthcare on essential services:

As a Swede I nust say I really don't get what you mean by that.
I guess the places where you get escorted from in the US are privately owned and not due to a law (but I could be wrong). The companies firing you for smoking might also have to do with a bit stronger labor laws in Norway :)
In the US, you might be protected by the Americans with Disabilities Act, which has some teeth. https://www.laborlawcenter.com/education-center/new-ada-guid...
I do wish people would think more about the scents they use, and for the love of god stop putting the unscented laundry soap in the middle of all the scented ones!
Of course, I don't mean to suggest that obnoxious use of perfumes should be encouraged, but for those who are extremely sensitive, it's perhaps worth a look given how rarely doctors seem to seriously prescribe exercise (I think part of the reason is that taking up a new form of exercise is intimidating and difficult to monitor for many people, and that not all doctors live the healthiest of lifestyles themselves).
