You're making a false equivalence because youre not considering the 'what for'.
I don't need a llama to get me food.
I don't need a llama to buy me things.
I don't need a llama to build me a house.
I don't need a llama to be okay with myself.
I don't need a llama to protect me from trees or fossilized bones.
And so forth and so on.
