Not that it invalidates your points at all but I played HL Alyx sitting down on an original oculus quest on a computer with a 1060 and an r5 2600. It was great but it and Beat Saber were basically the only two VR games that were fun enough for me to play for more than a few minutes at a time.

That quest has been collecting dust since I beat Alyx.

Really hard for me recommend spending several hundreds of dollars on hardware when there’s really only one game worth playing. But if you can find a cheap used quest or WMR headset it might be worth picking up and then selling just to play Alyx. Alyx is probably one of if not these most well optimized VR game out there. You really don’t need that powerful of a rig to play it.
