There are no useless body parts. Just incomplete knowledge.
In responce to being able to remove parts of the body: we aren't airplanes and we need to survive even grievous injuries. Otherwise we would die

The earlobes might seem useless, but you can use them to your advantage, for example you pull down on them softly to relieve and stretch the muscles
near the ear.
