There are still many issues that VR hasn't solved (and may never solve).
- You still have to wear a device on your head
- You still (can) get motion sickness and/or headaches
- There is still not a lot of great content around VR
- Many people still prefer the flat screen medium and content
The openness/closeness is only one of the many issues this solves, and it doesn't matter when all of the other above issues exist.
