It's fine if you don't want one, but my VR headset get used daily and was a great investment. Once you get used to good VR games, the rest of the video games in 2D just begin to pale in comparison. One example is Assetto Corsa (racing sim) which I could not win any races in in 2D standard mode, but when I played in VR my 3D sense of distance allowed me to actually race competitively enough to win for a change. Also it's just pretty rad to drive racecars in full 3D view, getting the full experience of moving at high speed.

And it's absolutely not true that there's "no applications" for VR. You just don't know about them because you're against it. In my household the primary applications are gaming and exercise. There are a number of VR games that require the player to physically move a lot, enough to break a sweat on every session.

IMO the only thing wrong with Apple's Vision Pro is the high price. I spent $1000 on my VR system and that was a lot. So when you get into the triple-thousand dollar ballpark, your market is just too tiny to grow into anything soon.
