I am sensing frustration on your part. Perhaps you don't like reading? When my students tell me they don't like to read, my answer is always, "Keep looking. You haven't found a book yet that speaks directly to you."
To answer your question, literature should be studied for a richer life. Without it, we miss out on so much. Think of all the places we get to go, people we get to meet, situations we get to experience without ever leaving our living rooms! Without reading about these people, places, events, we quite possibly would never experience similar situations. By reading about them, discussing them with others, thinking about how we would react in similar situations, we are learning. We are gathering information and tools for our life toolbox. Every book you read changes you...even if only slightly. You are a different person on the other side of it whether you recognize it or not. You are learning, collecting material, developing personality, discovering likes and dislikes about yourself. You are studying the human condition, and this is important because you are part of the world itself.
Reading provides for a richer, more fulfilling life. Can you live without it? Sure. Some of us can. I, for one, would absolutely wither and die if I could no longer read. But without the enrichment and fulfillment that reading brings, life would be considerably less luminous.
