The EM spectrum is pretty heavily utilised by a variety of uses and its not all that easy to deregulate spectrum. Much of the 5 and 6 Ghz spectrum overlaps with radars and other uses and has to detect collisions and shut down frequencies if it interferes. So its already a problem at the current spectrum use in a variety of locations and that will get worse the more spectrum is shared. Even with Wifi 6E we are only really talking about less than 10 gbps theoretical bandwidth, which practically even with a device using 4x4 (which none of them do) would be half that. That is well below the 32 gbp/s of Displayport 1.4a that monitors typically use and that is ignoring DP 2.0 and HDMI 2.1 standards that offer even more. Its a lot of spectrum that is required to reach monitor levels of bandwidth without significant compression (which is how VR headsets do it within 500 mbit/s on wifi 6@5Ghz). Its technically possible but not without significant costs to other users of EM spectrum.
