"Well then just dont get sick" is a bit of a stupid way of life. Getting sick is rarely optional.
Blue collar workers get injured. Thats just the nature of their jobs. If you work in a coal mine, your lung is fucked up, at some point. If you work in construction, it fucks up your back.
Wishing for medical care to be outlawed is not just a bit retarded.
Even if you're one of those wholly arrogant retards who think that people who "didnt manage to not be blue collar" - someone has to do it. Its conceptually impossible for the entire population to make it big. Even if every indivdual had the "chance" to be a millionaire, not all of them can be.
Insurance is just about the most basic necessity you can think of, to maintain society.
Or you can just solve it with outlawing insurance, forcing everyone who ran a streak of bad luck into crippling debt and then imprisoning them. Thats what they did in the middle ages. We progressed past that for the better.
