What if the cable is too cheap that it cannot be that good?

I am a huge..HUGE fan of the cables from Chris Sommovigo---the Black Cat cables.
Yesterday, I was at a store that has some excellent gear, most of it very pricey! The conversation got around to cables...and the pricing that some of them demand. The point that was brought up was: the value ( price) of some of the cables just cannot be justified...not only in the construction aspect, but also in the performance aspect. Couple of examples were floated ( we all know the usual suspects) and I mentioned that the Black Cat cables could easily compete ( and in most instances- surpass) with these examples. As some of you know, Chris’s cables are priced more than fairly---and if you take into consideration the performance that they give...should be an absolute nightmare to the folks who are trying to sell multi thousand $$ cable. ( never mind the fact that they are at least as well made, if not more so!)
Black cat cables are maybe an exception here--as their price to value equation is off the charts IME, but the question becomes...what ( besides bragging rights) does the ultra pricey cable buy you...if it is not necessarily a performance increase due to?
