Legislating that everything shall be a $50 20Gbps cable stuffed with impedance matched micro-coax and shielding on top of shielding on top of shielding just means that nobody can afford it.

USB-C is not and will never this thing that you are imagining. It is one commonly shaped hole, with all the incompatible connections of yesteryear now lurking in a mess of unreadable symbols next to each port. This one can charge. That one can thunderbolt. These can send out power, if you want to use your laptop as a $2000 portable battery. This one sends out video, but wait it's only HDMI, and only if that port over there isn't using its superspeed lanes.
