I'll go in the other direction. With a few exceptions, it is unfortunately true that "a business" isn't just "a way to make money," it's VERY OFTEN "the only reasonable way to accomplish a big-ish goal involving multiple people."
I say this as someone who started a business incidentally, my father had a big project that he and I loved the idea of, and I knew I could put together a good team to do the web part of it, and so I did. Money was NOT the primary motivator.
