Extending your simile, some devices need the equivalent of UDP in order to function within the size/power envelopes that make them useful. Bluetooth vs the nRF24L01+.
There are standards like this in highly interoperable systems, but there’s a cost paid. USB-C power delivery negotiation (beyond the very basic 5V3A resistor that people omit) is roughly as complicated as gigabit ethernet. That compute has to come from somewhere and it turns out customers won’t even pay for that 5V3A resistor - they’ll just use A to C cables and replace it when it “won’t charge” from a compliant charger. :) Average person probably only cares that USB-C can be flipped and that the connector feels less brittle than microUSB.
UPnP exists. Lots of what you describe exists. Between bugs in implementations becoming canon and a lack of consumer interest, no real conspiracy required. At least smartphones and tablets are trending in a good direction - Apple’s latest supports basic off the shelf USB-C Ethernet, displays, hubs, and so on.
