You believe it because you've been hyped into believing it. Speaking as a former member of the Society for Information Display I can say with no quaver in my voice that the compelling reasons for VR are no more compelling than they were in 2000, in 1990, in 1980 or 1970. VR is cool. For about half an hour. Then it's wearing, isolating and fatiguing. Always has been, always will be. DARPA pushed this shit as hard as they could back in the early '80s. There was no impediment to their progress. Yet they abandoned it by '86 because no amount of miniaturization or refresh rate addressed the fundamental problem with VR: we don't really see in stereo. We interpolate from mono, with heavily-lossy processing, because binocular vision gives us depth cues only to within what we can reach with our arms. Everything else is head position. Every VR setup you've ever seen (except one) uses binocular vision for the sum total of your stereoscopic experience. As a result, every VR setup you've ever seen forces your brain to do things it can't do. That's not going to change until we ditch the immersive glasses. Period. Full stop.
Eh. I've used a Vive. I've used a DK2 for an afternoon. It's not something I wanna do all day every day, but I can say the same thing about Overwatch or Kerbal Space Program, or basically any other game. Don't forget that for all its one-hit-wonder-ness, Guitar Hero was FUN. (To its target market)
