I take your point but have you tried the Oculus Quest 2? If you haven't, I would suggest you do. I think it's pretty compelling where it is now and I don't think it's too bulky for short - medium sessions. And with a stationary Guardian even.
Better, but a major breakthrough on multiple fronts is required. The lightest headset with fantastic resolution and response still won’t make the cut for widespread adoption IMO. You need to crack input/control as well as real life/meta transition. Can probably get there with enough iterative improvement, but it will be quite some generations yet.
