This is a disingenuous analogy - the reason people keep eating rotting meat is because there isn't a usable alternative for the vast majority. Fridges are unknown, to hopelessly overload the metaphor, to the masses and those that are aware of them are reluctant to shell out for the cost.

The problem needs to be solved at a more fundamental level - people should not have to be forced to perform a function that they are demonstrably bad at. Mitigation strategies like having randomised passwords and storing them in a shared authentication platform are only masking the reality that passwords are a bad way of performing authentication.

Not that I'm clever enough to come up with an alternative mind you, and not to suggest that I don't agree with your premise that using a password in multiple places is a bad idea.
