The reason VD is arguing the 'theoretical sale' and the reason so many are annoyed here with him is probably the same: excessive sales and marketing experience, where being tenaciously annoying often creates eventual success. It's like having this .001% chance each time you throw a basketball the full length of a court vs. a moving basketball goal, while blindfolded. If you had the chance to make 10k$ if you succeed, and an infinite amount of time to try it, you might consider doing it, even training and scheduling it day after day. Sure some might not want to try it. Some might give up. Some might just dismiss it as impossible. Some people would just be awkward with the whole process of trying it: 'not for me' 'uh...basketball, what?' Some might physically be unable. Some might have a phobia of being blindfolded. Reduce this down progressively from 10k$, and the odds of anyone trying it diminish even further.
And that's pretty much the same thing as trying cold sales (or, and mixing analogies, but: shivering alone in the freezing night of the Market My Product Wasteland). Some are probably better off not even bothering, but furious persistence really
can produce 'miracles' in this sense.
However improbable, I don't doubt creative badgering combined with fighting grassroots on other levels could produce a miracle here and there in the avenue VD is suggesting...
Either that or a restraining order.
Anyway, the same principle applies to the blossoming of annoyance on this issue of principle: VD has a .001% chance each time of convincing anyone here of the 'snake oil' that is the sales logic presented, but hammer it home again and again he did, like a true believer!
