If you are talking about needs from a Maslow's Hierarchy of Needs perspective, the yes, we technically don't need many things at all. I think that's just picking on the definition of one word. I don't think the argument to ban them stems from a lack of need, but rather, the negative use has so far unmeasurably outweighed the benefits. In which case, yes, I'd argue something so inherently negative should not be available.
