Porn can't make the big ticket sales needed to prop up VR. It's hard enough to get a payment processor because of how often charges get disputed and fears about touching the money for illegal and abusive material.

You can't be discreet about VR porning because it leaves you oblivious to your surroundings. You gotta plan ahead and really commit to the time and place.

Aren't all of them propped up by being tethered to some FAANG? I highly doubt they are interested in hiring the best and brightest to build VR porn devices.

I also suspect that the "kick" from porn is a voyeuristic one; i.e. most consumers would rather watch it than be in it.
