I wonder if this is something VR headsets can eventually fix by putting things at a longer focal length?

Maybe instead of a 50” screen 24” away, a 500’ screen 240’ away.

Do we really need VR headsets for this? Is there some material way in which just walking around outside, for free, is worse than strapping expensive electronics to your face and staying indoors?

See sibling comment. If studies are right, the dominant factor is about one’s exposure to sunlight, not focal distance nor focal variation.
