The huge problem is it is very hard to:

a) find a young, beautiful girl with very long hair (I estimate women between the ages of 18 - 30 w/ knee length or longer hair at 0.01%, i.e. 1 in 10,000)

b) find one willing to model

c) find one willing to model and do 'hair fetish' poses.

Just getting a) and b) is extremely hard. I have done photoshoots/videos in the past and let me tell you, it isn't easy to find these models (and it costs $$$ to travel to do photoshoots).

RealRapunzels have got some astonishingly beautiful women with great hair and even though they don't do any extreme hair fetish stuff, I still appreciate and enjoy these videos.
