If a Lightning to USB-C cable (which has existed for a while now) is a dongle then what is the USB-A equivalent ? How do you think people have been charging their iPhones to date ? And you realise you still need a "dongle" if Apple used USB-C on the iPhone ?

And why does your girlfriend need two sets of headphones when there is an included 3.5mm adapter with the iPhone ?

So many questions. Because literally nothing you wrote seems to make much sense.
