It's possible that WiGig 1 used as a VR headset wireless adapter is patented and complicating the situation. 

Otherwise, there could be advantages to using WiFi 6E instead of WiGig. WiGig operates at 60 GHz, so the signal is much more easily obstructed and dropped. 6E uses 6 GHz, which is just a little bit worse for signal penetration than 5 GHz, so the connection should be a lot more stable and reliable. In addition it has higher bandwidth than normal Wi-Fi, as it can use wider 160 MHz channels (which the Nofio does, plus it uses 2x2 MIMO, so it's double the speed). 

It is also a misconception that the Vive Wireless Adapter doesn't use compression. It does. It's just unnoticeable visually and in latency. Otherwise it would be impossible to use WiGig for the bandwidth of a modern VR headset. 

Nofio is also just a startup, they don't necessarily have the connections or deal making capacity of a big company like Valve. So you can't expect them to be able to source the most advanced components, especially for cheap.
