DJB is famously "extreme" in a lot of his positions and although his work is incredibly valuable is not a good representation of the typical beliefs of the community.
Ask yourself if you use this principle IRL? Do you give your cleaner the house keys and make yourself scarce so they can work in peace or do you treat them like an evil maid and watch their every move? Which approach has better long term outcomes for your security?
Counterpoint: do you give a cleaner the key to the house, or do you hand them a box with your whole keyring, your website passwords, the combination to the safe in the bedroom, etc?
