I didn't conclude that the email client needs to warn users about dangerous attachments- I mentioned that even if it did, users would ignore it.

But I do believe that UX needs to be designed according to the principle of least surprise, and those in the know (i.e. we/us), need to put in guardrails to keep people safe as they get on with their day.

If your hammer has 4,500 different everyday functions, 4,400 of them posing a danger to your fingers & bank account, but hammering nails is necessary for your job, for your kids' school stuff, and to interact with your government, then that's a closer analogy.
