I believe most insurance also covers the damage done by your vehicle to other property. So the upper limit on the total collected through premiums is somewhere between 0 and the cost of an expensive house.
It's actually more along the lines of whatever a person's life is worth. Also where I live the ~3 cars around me in traffic could each cost more than a nearby home. You can pretty easily destroy $400,000 of property here in an otherwise uneventful accident.
However, it looks like that is mostly due to more lawyers being involved in bodily injury claims. More lawyers involved points to a failure with insurance company's ability to properly adjudicate claims. When insurance is only about profits and finding tools to further squeeze your existing clients no one benefits. Insurance companies do not need more ways to rate me, they just need to do the job they get paid to do.
I don't really understand the point your are trying to make? You state that "insurance is about pooling" then correctly observe the dollar amount they charge you is just some sort of risk rating assigned to the individual.
Also if you ever have a large claim paid, you'll quickly discover it isn't about pooling at all. Every insurer will simple decline to quote you or simply quote you some insane price. Even without accidents I once got a quote that was obviously a response of "please do not purchase this policy" when I tried to get basic liability insurance.
