If insurance weren't ubiquitous, service would be cheaper, sure. And people would die or be bankrupted by treatable medical conditions like crazy. This is why insurance is so common. People don't like that kind of thing.
Given the system that we're in, you're doing me no favors at all by refraining from obtaining health insurance as a healthy person. You've decided that the risk of bankruptcy is acceptable while externalizing a lot of that risk.
