I appreciate your self-reflection on your comment and would say that your frustration is probably more with the fact that people (as an aggregate) don't learn as quickly as we would like. I offer this thought to you:

Not everyone has read pg's essay, even if they have, they may have forgotten it's contents, not agreed with it, or simply decided to ignore it while pursuing their startup ideas.

Listening to an interview, even one that repeats most of the same advice, can still be beneficial because it is a reinforcement of a lesson that still needs learning and because you may identify better with the Submittable guys as fellow founders after hearing their voice, than with pg as a distant ex-entrepreneur-turned-investor with his more dry prose.
