Basically, I would say no, since there are topics for which it is meaningful and rational to resort to arguments from authority. To name an example, if I want to know how you feel, the best thing to do is to ask you.
But even if you don’t agree, let me point to the distinction between
- the use of such arguments as a way to close a discussion (e.g., “It is the case that X, because an authoritative source said it”)
- the use of such arguments as part of a discussion or as opening a discussion (e.g., “An authoritative source tells us that X, how shall we understand it?”)
