The point is not whether it is correct and necessary, but that its existence makes the argument that it is indeed so. What you mention is actually the insight that "it may not be". But you reach that idea _against_ the argument its presence is making.
That is, you find some code. Its presence says "I'm here for a reason", your answer of "maybe it's just because..." comes as, precisely, an _answer_ to that argument.
Neither the argument itself nor your answer are necessarily and always correct. This doesn't argue that point, just that the presence of a piece of code makes such an statement.
