I have had many successful projects where we spent approximately zero time on estimates. The fact that a successful approach is culturally seen as illegitimate to even talk about is a great example of why I wrote that last paragraph.

I, and others, don't agree with the blanket statement that "no estimates" is not a legitimate argument in any scenario. Can you expand on why you think there isn't a single case where estimates don't add value? Similarly, is there anything specifically in that post's claims that you think was incorrect, leading to their false conclusion?
