"Here's some ways in which it can work using a slightly different but still as widely used commodity technology" (wired LAN)
"No, that is unreasonable, wires are unreasonable"
Like, it's SUCH a simple solution: use wires. That's how I can stream games from my computer to my parent's house at 1080p60 with only about 30ms latency over domestic broadband connection, for example.
Also, sometimes you can get really lucky with wireless on 5ghz - see streaming in VR as a prime example. The developer of Virtual Desktop for the Quest has done some great work getting a really solid low latency VR feel; I've been able to stream games from rent-a-VM ShadowPC servers without feeling the lag.
OK, so pro audio is a different beast and is even more sensitive to latency than VR, but here people are having fun with this tech and clearly it's working for them!
