The problem is that you assume that everyone wants to make a business from book writing. Most technical authors don't want the trouble of book production and sales because they already have a good paying job. They are just interested in having their names in the cover of a book. For this purpose, publishers do a reasonably good job -- certainly better than having to do all by yourself and end up with a low-quality, low-selling "book" in the Kindle store.
