They already have you covered then. You'll be getting a comparable or marginally worse setup than couch gaming. It brings none of the benefits of the medium. There is no reason to use VR to game in this way. Perhaps you and some others want to do it, but it has no additional value prop to most people and is not what people mean when they say "VR gaming".
I may be in the minority (although that very much remains to be seen) but I think this approach gives you the only actual benefit of VR, namely immersion. I play video games to relax, having to jump around to avoid shiny lights is the opposite of relaxing.
