It's simply another peripheral to improve immersion. It's great for people who want to experience cool stuff. It's also still early so it's just gonna get so much better in the near future.
How you think it will ever be as big as a normal screen is beyond me. People have shown time and time again that comfort and accessibility go above everything else, including immersion. No matter how comfortable and accessible VR will become it will never beat just sitting on a couch and pressing a button. Don't forget that the majority of gamers are casuals and even the majority of core gamers will prefer the more standard method. It doesn't really matter how much stronger the VR experience is.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
