If I want to make a crazy phone that is 2mm thin and needs some special charger, I shouldn't be banned by the government from doing so. And if I have some charging port that I think is better than USB-C, I shouldn't have to lobby the government to get it implemented.
Right now new phones either have lightning, or USB-C. Seems pretty reasonable to me. USB-C is not faultless - imagine if we had been stuck with micro-USB instead.
How about the government leaves us alone and lets us make our own decisions. I think that would be nice. Just make people pay for their externalities.
Hopefully in practice, all this means is that Apple will include a lightning to USB-C converter in the box.
