Because insurance prices are higher, and they make a percentage of the total payouts. All the insurers make the same actuarial calculations so there's no significant difference in pricing between them. All the banks pay the same insurance price and pass it on, because none of them care about security of your goods or information (according to the parent).
Interesting; I could never stomach actuarial textbooks well enough to gain much more than a high-level view of this industry. So higher-price policies are higher profit? I had always assumed the higher prices reflected the higher risk to the insurer, and even in a competitive market I would assume that the profit margin per policy would be roughly comparable between different types of policies.
