Remember when the ports that did a thing, only worked with other cables that were meant to do that thing, and generally if the cord fit, it was in the right spot? That was great, now I have to look at tiny little symbols, and hope I know what each obscure symbol means. The progress is amazing.
I literally have a box of pre- USB-C cables. S-Video VGA RCAx2 Coax RCAx3 VHS hi-fi optical HDMI DVI-A DVI-D and a LOAD OF SIMILAR crapola! the box is 12" x 18" x 12" and it's FULL!!! Good riddance!
Won't that just be replaced by the same box full of USB cable that can only do displayport, some that can only do networking, some that can only do storage, and some that can do a combination of the previous, probably at different speeds... The only difference would be that when you need a specific one, you would have to try them all until it works ;)
If each of the types of cables is probably less than $5, how do you get a $70 price tag for the combined all-capabilities cable? I'd be surprised if it would cost more than $10.
Because that's how American brick-and-mortar retailers make their profit: they take a cable that you can buy on Ebay for $5 and mark it up to $50, while keeping their prices on big-ticket items (like a TV or laptop) somewhat competitive because people price-shop on those things, but not on accessories.
Have you seen the prices for VGA cables, cat5, etc. at Walmart, best buy, etc.? They absolutely will jack the price up because they know the only people who buy that stuff there are ignorant or too desperate to wait for shipping.
Brick-and-mortar prices are constrained from the top by competitive pressure too. They won't be selling full-capacity USB cables with 10x markup, because they'd lose even more business to on-line stores.
