@Joseph: The question is whether it is considered ???? ????? ??? when the end you are trying to reach cannot be achieved by any other means. Is “?? ????” defined by the means or by the end? By ??? ???? ?? ????, the Rishonim write that wearing tzitzis with kilayim may not be considered ???? ????? ??? to say that you should wear a shirt of different material, because you want to wear this shirt. Once I am wearing this shirt, it is ?? ???? ????? ???.
Of course, this may be chalk and cheese – the two things are not remotely connected. But the definition of “unnecessary” doesn’t have to mean “can you live without it”.
