I’d rather apply Hanlon's razor here. And for your example: my employer finds it worthwhile to maintain a security person to be equipped and trained to take adequate pictures of employees in each office. It’s a linearly scaling cost that could be optimised away. But, it removes failures modes (contract photographer not delivering, employee missing an appointment, …) with total expected impact exceeding the cost of a camera and explaining to a new guy which corner of the office has the lightning set up for three point portraits.
