Haha, or unless you're a part of a community in the middle of somewhere? There are several communities (just that I know of) where many (not all) of the participants live entirely without money! Here's one http://www.auroville.org/contents/95.

I just wanted to add this in, because it felt like (I may be wrong) as if you were saying it was a fundamental fact of society to have money (instead of a choice that we either consciously or unconsciously make). To further add to the point, our culture places far to much value on one form of capital (financial) nearly ignoring the rest (living, material, social, cultural, intellectual, experiential, spiritual) where people from monks to commune dwellers have found systems to live without money... Just wanting to expand the conversation :)
