The US is unwilling to do this, not incapable. This is because the US values innovation and market choice highly. The very port that you are praising might not even exist if the US dictated standards. We would still all be stuck with micro USB connectors or maybe even barrel jacks. Apple created the lighting port because at that time nothing existed that would do what they needed. Only later was the USB-C port created that leveraged many of the same ideas. The lighting port lasted for so long because it’s a good design and in some ways superior to USB-C. Had Apple licensed the tech, as Samsung and Nokia had both been interested in doing, we might have been using lighting ports for everything a long time ago.
