If you look at the product, there is at least some innovative engineering involved. They didn't just paint the wires a different color and jack the price with every iteration, or every color change (if the shoe (fuse) fits...).
What they charge for it, and what people pay, is of no concern to me....we call it "free enterprise." This is no more "madness" than what you see in many industries selling luxury items. If you don't want to pay $10K, or don't have that much money for speaker cables, then there are plenty of other options. For example;
Neotech has a speaker cable with similar (but not quite the same), single-wire winding geometry, but in a less complicated design;
