For me, the biggest reason I think a degree is necessary is because it is comprehensive. Self taught people are going to inevitably have multiple holes in their understanding. And worst of all, they will be ignorant of where those holes lie and how large they are. This is not my experience. Self-taught people are often much more aware of the potential for knowledge gaps, because they've had to learn what to learn. Part of self learning effectively is appreciating the complexity of a topic and choosing what to focus on, rather than just be lead through it by a teacher. Their default position is one of humility, rather than the often common attitude of "I have a CS degree so I know what is happening at a network layer, OS layer, memory layer, application layer, and system layer, and code layer". (Hint, you don't).
