I think it's more of a rephrasing of not wanting to live. And to not live, one must die. You also don't have to have something tangible in order to want it. People want to feel loved. I love music, but you can't exactly call that tangible either, you can't touch the sounds (let's not get into insane physics here, we all know what I mean). Not everything someone wants or needs is physical. Concepts are equally as important to the human brain.
