This bothers me a lot - the idea of using anonymous "Chachamim" in arguments. I don't understand why is it important or useful to hide their names.
The Mishnah uses it extensively and makes it very difficult to trace Rabbis' opinions. I understand that it started in the Torah as Rashi says: "why didn't the Torah specify their names? To say that every Sanhedrin and its Sages counts".
But the Zkenim of Dor Hamidbar were all secondary to Moses, as opposed to Mishnaic Machlokot.
What is the point of letting the Sages stay anonymous in important Halachic arguments?
