You nailed it on the head. Often times, with new technologies that are a step function jump, rather than an incremental improvement, people think "what would I do with it that I already do, but faster/cheaper/easier", rather than "what new things does it allow me to do that I couldn't do before?" The latter question is the correct one to answer with something as weird and new (new to consumer/pro-sumer) as 3D printing.
