Unfortunately I believe the only answer you will get to "why" is excuses. The why is obvious. High chance of failure coupled with high cost of failure.
My point was I can not find any posts on the internet where someone could reliably differentiate between a $100 cable and a $1000-$10,000+ one (and that is what this post was originally about). You would think at one of the large audio conventions some high end company with their uber expensive cables would have some superlistener who could show the world there is a difference. Why don’t they do that?
