I guess philosophically speaking, it is pretty rare for an individual to develop a written "voice"/style distinct enough to warrant this kind of protection. Not least because only very few people would ever be able to mistake a "fake" of your written style for the real thing (because very few would be familiar with your style in the first place) and even if this happened, the likely consequences are almost always negligible. It's simply an edge case and any solution to it that I can think of would produce more problems than it solves.

Your likeness on the other hand is pretty unique for most people in the world and the technological ability to produce convincing and arbitrary copies of it has very obvious and frightful consequences. Resolving this problem is of tremendous importance for social cohesion.
