> Credit card companies already have the perfect "security" measure: retroactive limited liability for stolen cards. Nobody loses money because someone steals their credit card.

100% on that. Money is lost all the time, but thanks to that retroactive liability, the bank and/or merchant loses it instead of the consumer. Security for the consumer is already as good as it could possibly get, so they're really saving themselves and their merchants. This is a good thing, because they have a much more direct incentive to save themselves money than to save you money.
