It's very difficult to manufacture both soaps and creams in the same facility, especially an artisan facility, where space is considerably more limited. The storage time required for a cream to rot can range from anywhere from 6 months to a year, depending on the ingredients and storage conditions, so storing it for that long can become problematic. If you have something especially popular and run out, it's not just a matter of making some more and letting it age for a week or two. It takes months and many people are simply not that patient.
Additionally, the methods for manufacturing shaving creams are far less well known than those for making soap (consider the fact that before LASSSCo. published their tutorial on B&B, there were far, FAR fewer artisan shaving soap manufacturers), so access to information is a heavily limiting factor.
Finally, there's also a lot of truth to the idea that a perception that soaps are better, whether true or not, significantly influences the market. People want soap. They prefer soap. There's an overwhelming idea that soaps uniformly last longer than creams and that their performance is almost always superior, neither of which is true in my experience. It's likely that, as some of the larger soap companies continue to expand, creams will start to become more common, but, for people making it in their kitchens in crockpots, it's probably not worth the time or the effort.
