Because camera manufacturers makes more money building a whole camera and update it incrementally, just like Apple does.
Then there's also the issue of compatibility with the software. 3rd party lens is a good if somewhat basic example of modularity. They don't AF as fast, accurate and reliable as OEM lenses.
To be honest with you, I think PC modularity came from the nerds who modded their machine, then a whole market opened up because of it. It's the same with cars and aftermarket parts. So if you want the same thing with dslr, people will need to start modding their cameras in big numbers.
Yes, given there will be a lot of issues to overcome to get such project started. Manufacturers design firmware specifically in a way to protect their products and to give third party manufacturers a hard time to reverse engineer and to make the lens work on future camera models. On the other hand this could be an advantage also for this futuristic module camera since it could be more compatible with a bigger variety of gear on the market - even a lens AF might not work as perfect as directly mounted on the same manufacturer's camera.
In the beginning this would be more a niche market, but I can imagine that people would jump on this wagon if there is a big enough of cost saving advantage for a good managed quality of such camera.
