While I think your argument is very valid for consumer-level interfaces, I don't think it holds for more skilled and specialized tasks like server administration. Someone who's never done it before should be following a guide regardless (for security reasons if nothing else), and if you set up servers often enough that you don't need to at least glance at a guide or checklist to make sure you're not forgetting something, even the more arcane commands are going to be second nature to you.
