>The key problem with your assertion is that at the time insurance is purchased, nobody knows who will be the victim or whether there will be a victim. Purchasers of insurance would rather spend a little bit of money just in case a bad outcome occurs, so they don't bear the full brunt of that bad outcome. Those who don't end up with a bad outcome don't get their money back, which is why the system works.

You say that my comment was profoundly misguided, but your comment right here is just a rephrasing of mine Someone with risk spends a little bit of money to help absolve themselves of that risk. If a bad outcome occurs and they fall victim to that risk, they don't bear the full brunt of that bad outcome because money is shifted from people who didn't fall victim to that risk.

Regarding you point about probability based pricing of insurance, we have collectively decided that we don't want health insurance to function that way. If it did, it would lead to the preexisting condition problem in which a person cannot afford insurance because they have a condition that requires expensive care. We instead subsidize their policy with a price increase on everyone else's policy.
