The purpose of presenting isn't for you, it's for audiences. The thought process or lack of it will happen either way, and can be accomplished either way.
Not really a counterpoint, but a “yes, and”: I’ve often made an “internal” presentation that is mostly for myself and maybe a few others, which distills the key concepts of something into a coherent narrative. While it can help others, I also have found the process of creating a presentation, outline, or summary helps me to properly organize (and sometimes change) my thoughts at least as much as it helps convey those thoughts to others.
