Why buy insurance?
People's value of money is not always linear.  Consider an individual with $1000 in the bank.  I'm going to look at amounts of debt by orders of magnitude: Now its pretty easy to see a order of magnitude increase in impact from $100 to $1000, and it becomes slightly worse for the $10,000 case due to debt.  However, one more order of magnitude, going to $100,000, and suddenly it becomes hard to argue that there's a mere "order of magnitude more hurt" than the $10,000 case.  From the cases I've read, those sorts of situations can be far far worse than the monetary cost could convey. Insurance companies are in a good position to absorb $100,000 of debt if something happens, far better position than the individual.  They rely on the central limit theorem: in general, they don't have to pay out all at once. The insurance companies have their limits too.  When hurricane Katrina came through, the insurance companies had a tremendously difficult time dealing with so many claims all at once.  Just like the individuals, they found a sudden change in how much value they had to put on their monetary debts!
