Are you being literal in the second half of your sentence? I, as well as everyone else, has had loads of companies ask me about my opinion as a consumer. I've never had a company ask me "How would you sell this to someone else"? Have you? Do you actually state that question?
The statement "would you ask a fish, how to fish" comes from the dating world. I was tired of not dating despite doing what my women friends told me they wanted, which is wrong. I'll give a personal anecdote. Women looking for serious relationsihps on dating apps will say they will left-swipe or reject someone with just a picture of their nude upper body without a head. That's not what they want to see, they say.
I followed their advice for a while. Then I ignored their advice, I changed my profile picture to a picture of my nude upper body (I'm male) without my head, and shortly thereafter I had a great girlfriend I was in a monogamous relationsihp with, wherein we both deleted our dating accounts shortly after first meeting.
The fact that women say this is not what they want (when asked what they're looking for from 'pitches') is absolutely irrelevant to how to attract and make them happy. This isn't some kind of meta-commentary on consent or anything like that, I am just saying that it doesn't matter that they told me this is not what they want to see. Because it doesn't matter what they say, it matters what htey do.
It doesn't matter what Garry says, it matters what he does, and no, neither he nor anyone else actually invests on the basis of the points he's enumerated in the article. I point this out by showing what it would take to fail any one of these filters.
Also notice how powerful this comment has just become, after I shared a personal story from the dating world. (At least this is my personal judgment/experience - perhaps you don't find it any more convincing than my more rigorous argument upthread.)
