Why put a substandard camera experience on a phone compared to dedicated cameras? The same reason some people would want a lesser version of VR using their phone, because it's what they already spent a lot of money on and they always have with them.
So were the first cameras on phones. They were horrible, and had very specific use cases such as after an accident to get someones license plate, they were never used to enjoy looking at photos like you do today.
This is clearly the beginning of VR, and has limited uses as cameras on phones did back in the early days. Knowing this is how history advances, why would you be against progress? Without people starting these ideas and pushing VR forward, it won't progress nearly as fast as it will if the general public gets to experience it somewhat using their phone and a cheap headset.

The analogy between VR and a camera is a false one. I've already posted why. Not going to type that again.
