I did misread your first post, I thought you were paying $70 per sensor, not $35. If you went to Costco, over the phone they tell you it is $70 per sensor but then when they actually do it and use the Costco discount card (my friend’s insurance will not pay for this, and if you are a member there is their own discount card that they add to your account), then the price goes down. I think over the summer he got 4 sensors for $150 (I saw the receipt at the time) paying cash or credit with the Costco discount. They will also honor Good Rx but that was more than the Costco discount. While not as good as yours, for no insurance it is not bad.
Here is my issue. Many accidents are the fault of someone, which is your issue with so called life style diseases which you think should not qualify for insurance. With accidents there are many fault related causes, often more directly related than the lifestyle ones. You drank too much and fell. You were texting and hit someone. You rode a motorcycle without a helmet in the rain. You went skydiving. You did not wear a seatbelt and so on, endlessly. Unless you judge every situation at the emergency room door, how do you decide culpability. Plus if someone is unconscious it is the job of EMTs to render aid, no one asks if the 30 year old victim wants to be taken to a hospital, they take him.
As for your other comment about lifestyle. If I have learned anything over the last years of keto, it is that obesity is not a choice. If you read Jason Fung, he talks about obesity being another symptom of metabolic syndrome, not the cause of it. Sure obesity is the last permitted prejudice but hopefully with education that will change too. And yes, there are people sitting on their couches eating pizza, beer and doritos all day but most people try to eat healthy and most obese people, especially women, do not eat to excess but still cannot lose weight.
I can fast for days and have, exercise, lose a pound and gain it back the minute I have some lettuce or a piece of meat. Meanwhile, I know people who can eat anything and not gain weight. Every body loves homeostasis and fights to maintain it. This is one reason some ridiculously high number of people lose weight only to gain it back in 2 years
