Because it's a great way to transport taste, whether it's tofu, Seitan or something like Beyond Meat/Impossible Burger. Yes, you can prepare awesome veggie food without it, but it's a great way to get people started without having to miss anything. Kebab/Döner without veggie-meat just doesn't do anything for me, for example. I don't get why people are confused about this. You've grown up with certain expectations of how food is being prepared so it should be obvious that you're interested in supplementing the parts that you don't want to eat anymore with something that's compatible with the way you've been preparing food your whole life.
