Hakatan- that logic is so backwards. They get reward for learning so it therefore must be permitted. But in order to prevent them from learning Torah improperly, they are not allowed to be taught. Therefore, the only permissible way for them to learn is completely on their own with no teacher? That would only exacerbate the problem! Not having a teacher would guarantee that they would learn it improperly… Isn’t that what Chazal is trying to avoid? How could they permit learning Torah Shebeal Peh but only without a teacher in order to prevent them from learning it improperly?
