i think if you wanted items rather than necessary parts of life such as oxygen and water, you should not have phrased your question as “can’t live without”. The non-dramatic Flutherers realize that there are very few things needed to actually live. Now, since your Q is more along the lines of “what materials/goods would you prefer having to improve your life?”, well then my answer to that Q would be my car, mp3 players, laptop and internet.
