Nope, health insurance isn't insurance because literally everyone will need access to health care at some point in their lives. 100% of us will die of heart disease, cancer, trauma, etc. It's like if we had a 100% chance of houses burning down, we wouldn't call it fire insurance. It's not insurance because it's intended to be consumed, it's a communal pot.
Further, no matter what there will be more things wrong with us than resources to deal with it so the other goal besides efficient administration of a health system is rationing access to care.
No need to profit here, there's plenty of other ways to make money in the world.
All these "the ACA raised my premiums crap" is just that. You didn't have heath insurance before, you had a program that you thought was health insurance but would have absolutely bankrupted the average person if you ever needed to draw on it.
