But even those non-tech people should have some USB-C cables lying around at this point

Dont most people keep some devices permanently connected to the cable it came with though? I don't use my monitors USB-C cable to charge anything else. I don't use the quest link cable for anything but the quest. In theory it's "one cable for every device" but in practice the only place that happens is in a backpack power bank or car. Every device comes with its own cable and whether the new iPhone comes with a USB or lightning cable all it does is add one more cable to your collection.
