Part of it is that the cost to play VR - which is primarily the time cost - is too high for the experience you get out of it. For example, the only games that provides a true VR-only experience you can boot up on a dime are Beat Saber and VR Chat - other VR titles tend to follow the pattern of "<existing genre> but in VR". To add, you need 2x the processing power since you need to render the game twice, so you are going to take a hit in visual fidelity, AND you typically want 90fps or higher to avoid motion blur, which raises the bar for playing any high-fidelity VR game (at least until generalized foveated rendering APIs become available and headsets implement it).
