Two good reasons:
   1) The unique quality of viewing a slide by "transmitted
light", that is, the brilliance and color of a slide when one
is looking straight at the light shot into the eyes through the
slide and the viewing lens.  IMHO, this is as much a part of the 
beauty of Realist photography as the stereo!  I noticed this effect
years before I shot stereo, while looking at 2D Kodachromes through 
a lupe with a lightbulb in line with the slide - sunshine gleaming off 
metal objects really looked like sunshine (not matched in video, prints, 
or slides, projected or viewed in a hand viewer), and the colors took on
a new realism as well.
    Only in stereo is it easy to provide direct "transmission viewing"
of the same scene in both eyes at once. In a Red Button viewer,
especially one modified for a halogen bulb, this quality is appreciated.
    This is probably a major reason the Realist found appeal long after
interest in stereo cards had been more or less lost.
    I have tried to get this effect from 2D slides in a practical way,
but, the closest thing to it, a Sawyer Bi-Lens, loses some brilliance in
the splitting mirrors, and the image is too small.

2)  The price of a high-quality digital projector is still 
astronomically large, and, given the relatively small market
for them, will likely remain so for some time.  By converting
a high quality digital image to a high quality slide, one could
use an existing projector to project digital images and artwork
to an audience at a minimal price.
   Look at it this way - a 2D slide projector is available used 
for about $10, 1 storage medium (slide tray) stores 140 16GB image
files in a non-volatile, EMP-proof medium, and you can switch from 
one of these 16GB image files to another in less than one second.
