Connecting over a cable is trivial: you detect the connection and that's it, and the user physically sees the connection between the devices.
Connecting over radio requires pairing, that is very frustrating when it doesn't work. Pairing is annoying so devices try to automatically reconnect, but then if you pair with multiple devices, it brings frustration because it never automatically connects to what the user wants.
Whenever cables are a possible solution, they are superior.

Everything's frustrating when it doesn't work.

This is a solved problem, plagued by technology fragmentation. You could very well save the necessary information for discovery and pairing onto an NFC tag and use that to access the network (further authentication might happen, if configured).
This is basically never done on WiFi because you cannot assume a client host has a NFC reader (let alone proper code handling the tag and the information).
But it's done in the world of bluetooth: some big-name headsets (Sony IIRC) can do bluetooth connection negotiation via NFC. You activate the feature (dedicated button), tap your phone and off you go. No pin, no pairing annoyances.
