As you mention, this is trivially true on the level of the sensors. We know cameras are enough because human brains can do it with eyes (biological cameras).
But there is no evidence that we know how to write software for the processing part of it (to an acceptable degree of safety) with cameras only, nor that the computing power on-board is up to the task.
How can you say that hardware package X is sufficient to implement something that has literally never been done before?
