Unless materials science advances to the point where a display like the Vision Pro weighs as much as a pair of glasses, I don’t think there’ll ever be mass adoption of wearable VR beyond anything more than a novelty, for exactly the reason you stated.
Wearing something heavy on the front of your face is simply not a pleasant experience.

Beyond 2 is 107 grams. The new M5 Vision Pro is 750 grams. It's easily doable, but Apple deliberately makes them heavy for some reason.
107 grams is still pretty heavy. Regular glasses are 35 grams or less. My sunglasses are below 20 grams.

the steam frame is apparently 440 grams.
Vive Flow is 189 grams btw
Beyond 2 has almost none of the sensor suite, no eye tracking, no meaningful compute, no pass-through video, no inside-out tracking, no gesture control, and requires two to three entirely separate units set up around the room to do any outside in tracking, yet it still weighs 4-5x what glasses weigh.
Just the displays and lenses will outweigh glasses considerably and there's nothing to strip back when you're down to display and lenses. Throw in a chassis and head strap and you're pretty far from glasses in weight and ergonomics.
