I couldn't agree more. However it kicks off (character, a song, a joke) you have to know what you're writing about. Writing is one of our most human devices to try to apprehend and comprehend the world we live in (nature, society, politics, relationships, everything). It's a translation of events and situations into a whole new semiotic system, the story. It's building meaning. Through story, we get a little bit closer to the meaning of whatever we're trying to look at through the telescope (or microscope, by the way). If we don't know what we're looking for, then how can we hope to invite anyone to travel with us along the path ? It's not absolute scientific knowledge, it's emotional experience. Without a concept, how can we go anywhere? As a writer, I am absolutely frightened of irrelevance.
It's a shame that some cinematographies have misunderstood movements like the French New Wave and thus you can find screenwriting teachers encouraging students to write "poetic" scripts - about "life", about "everything", talking with utter disregard for "concept" or "theme" or anything that makes story work overall. That's part of what makes them such amateur cinematographies.
