2. and 3. have again nothing to do with the question. Plaintext passwords are obviously unsafe material, but that's not the point of the question.
Nuclear material that leaks its containment is bad no matter what, how is a hashed password leaking a bad thing is the entire question and you're only addressing it in 1. but I don't find that convincing. When was the last time a practical attack was found on a hashing scheme that wasn't already obsolete 15 years ago?
