Not sure where you live but almost everyone needs money in today's society. Unless you are a part of a tribe in the middle of nowhere or something. Generally the self-sufficiency can be done with something of value to a person and not money.
I do get what you're saying though.
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 :)
In a general sense, the behaviors are similar to money since it is something of value to incentivise and motivate the behavior of someone. The fact there are those communities that live without money is true but they wouldn't live that way if there were no benefits(value) of living that way.
