Because VR is expensive and the value of the experience is limited. Decent VR experiences require space. Room scale requires, well, pretty much a whole room to play it in. A room free from obstacles. An entire empty room just to play a game. I have one such room, and several times I've found that games still insist on placing objects outside the designated walkable area. Most people do not have an entire room to dedicate to VR. And most VR experiences really aren't worth it. They're largely novelties rather than something you want to interact with every day. The only exception I've experienced so far is Beat Saber, but even that with it's minimal around-the-room movement frequently has to throw up the guardian because I swung my fist too close to a wall.
