Totally agree with this point. There are several advice that pg and similar roles give which are not universally true. I reiterate your point that "doing things that don't scale" is meant specifically for searching for 1-1 user experience advice.
A similar exmaple is "Make something people want". This is generally true advice in focusing your efforts on solving customer's problems. Yet, this is disastrous advice if taking literally to the fullest extent (you can only imagine).
