The problem is untethered VR in the real world means shit graphics, shit battery life and a bulky HMD that generates more heat than the sun.
I can see you've not used one. The Quest 3 has graphics virtually indistinguishable from a wired headset. Just because it's standalone doesn't mean you can't use your GPU power on your PC. Actually I lie since the last wired headset I used had a lower resolution, so going wireless streaming with the Quest 3 was a leap up in graphics quality compared to my previously wired headset.
I get more battery life out of my headset than I am comfortable playing with. You can only run around the living room for so long before you want to sit down, and if you want to sit down, ... plug yourself in you literally have no further downsides compared to the tethered option. If you're comfortable tethering yourself, then tether yourself for unlimited playtime.
The Quest 3 on launch was smaller than any other HMD on the market, it was the opposite of bulky. You want bulk, buy a tethered headset. Untethered ones aren't bulky in the slightest. Literally every other headset released is setting small size records.
Generates more heat than the sun? You have that backwards. Heat is generated by my GPU. The headset doesn't generate any perceptible heat on my face and the front of it is lightly warm when I take it off after a gaming session. On the other hand when I use PCVR I walk back into the room with the PC, that room is very warm.
There are enough people using VR for flying/racing/space SIMs for there to be a market for tethered VR.
Yeah I'm one of those people, and I will not buy a tethered headset. There's just so many upsides to non-tethered and you've yet to point out a downside that wasn't simply the result of your ignorance.
