No, because the amount of money you have in a bank account accumulates linearly, so you can only pay up to what you have put in. With insurance, you can get a payout more than what you have contributed up to that point, which is necessary for covering catastrophic damages.
But in this hypothetical the insurance company has perfect information, so they won’t sell you that policy that has to be paid out for more than you’ve contributed.
It’s just a thought experiment, but the more information they have on us, the more relevant it becomes.
They can’t predict the future, they can’t predict exactly when you’ll get in an accident.
Perfect information means they know your risk level to the best possible accuracy, which would really only apply to populations.
Perfect information means they insure 1000 people and predict they’ll have one bad accident per year. After ten years they covered for ten accidents. All ten could have occurred in the first year and they would still be correct.
Sure. I can’t speak for Scoundreller, but I don’t think it was meant to be particularly interesting, just pointing out to wbl that if insurance was to become perfectly fair, it will also have become pointless.
There’s a pretty big leap between perfectly fair and having perfect knowledge of the future. You can know that a fair coin gives exactly 50% chance to flip heads or tails without knowing what the outcome of the flip is going to be.
The original context was unsafe drivers, with the gist of the response being that when you have everyone paying for exactly the costs they themselves incur, insurance has become meaningless.
It’s hyperbole of sorts, but it highlights that until such a time, raising the cost of insurance doesn’t just punish the people who actually cause the damage.
Except insurance also covers for costs that are not your fault or not anyone’s fault. An insurance premium could be divided into two components: one based on individual risk and the other component based on no-fault risk that applies to pretty much everyone equally. How are you going to get bad drivers to pay for hail damage? How are you going to get bad drivers to pay for a tree falling on your car? How are you going to get bad drivers to pay for an accident caused by a random tire blowout?
The personal risk component can be accounted by “perfect” information and that component can get bigger or smaller depending on your definition of perfect, but there’s another component which can’t.
What if you have perfect information and conclude that your chance of being in a terrible accident, requiring tens of millions of dollars of medical care and property repair, is 1% for every billion miles of driving, and you’re the unlucky person who happened to be behind the wheel. Will you have enough money in your piggy bank to cover it?
Maybe you could argue you shouldn’t have to cover medical expenses if we had a single payer system—the money to mitigate medical risk from driving still has to come from somewhere.
Maybe you could argue that damage to property should come from those property owners’ insurance.
What if you don’t get into a terrible accident, you just get into a boring accident where you total your car and don’t hurt anyone. You know the odds of this are low, chances are it won’t happen in your life, but it will probably happen to someone you know. What if it happens to you, when you’re very young and have a new car? You haven’t had a chance to put away any money in your piggy bank yet. You need to replace your car now. How does a piggy bank help you?
