Doesn’t strapping on a VR helmet kind of counteract the fun of being outside? Might as well just load up a nice outdoor scene as your background environment

One wouldn’t even need to go outside to want it. This could be the ultimate standing desk — one that you can bring with you to the kitchen or to the basket of laundry.

Why would you want to bring your desk into the kitchen or to the basket of laundry?

Not being flippant -- I really think that's the big question.

Current AR/VR (Vision Pro included) lets us do desk things at not-desk places, but why would I want to do that?

Only you can say why you would, so I can't help you there.

But, for me, for example: to GSD around the house while one needs to be in a Zoom, so that menial chores aren't waiting for me when I'm off work. Even Airpods let me do that somewhat now, but at the expense of missing slides or what's being shared on someone's desktop.

I enjoy the breeze and sun. Plus the smell of my garden

No, a desktop background doesn't come within 100 miles of being physically on your patio when it's nice out (or when it's terrible out; either way, it's not the same experience).
