Yes, titles need to be better at seated play, because it is a reasonable way to play, given almost no one has enough room to actually walk around.
But the entire point of VR is the controllers, not the headset. The headset is a huge pain in the ass, annoying, blurry, and tiring to use. No one would put on a headset if it were possible to transfer hand movements to a game world any other way. The monitor has to be glued to your face, but that is a downside, not the benefit.
