Without any formal organisation, things cease to work so well. On a smaller scale, what if everyone decides they want to be a tailor and no one wants to farm? People need to eat, so everyone ends up having to farm on their own to provide themselves with food and continue tailoring. But this becomes wildly inefficient because centralising production of food would allow considerably more time to be devoted to other things.
And it's not true that communism doesn't work, that's just historically inaccurate. Look at the Israeli kibbutz system, which lead the world in agricultural development while it existed. Anarchist communes in Spain were likewise wildly successful. People like to act as though they were good but "couldn't last", but each was brought down largely by external problems or internal problems having absolutely nothing to do with their political or economic systems. It's simply untrue that no work gets done with tangible individual rewards in such situations. Even if you don't believe that humans can contribute for individualistic moral reasons (despite a probably genetic disposition toward such reasoning), you have to completely ignore the enormous social pressure generated in such situations and the social rewards that come with contribution.
You can organise societies without money that function extremely well, but they still need to be ORGANISED. Even if everyone is willing to be nice to each other and help out, you need to figure out what needs to be done, how it needs to be done, and how best to divide up the labour. The key difference between anarchism (which is really what you're describing moreso than communism) is that people aren't FORCED to do things, but do them because they need to be done and the people recognise the utility of their labour. But the people still need to know what needs to be done in the first place.
And yes, people are greedy. People are also lying, cheating, murderous rapists. We (mostly) don't just say "well, that's how people are, so we shouldn't try to change that", we use our understanding to try to modify behaviour in a way that would benefit us as a group. If you think that anarchism and communism are a bad idea, I strongly disagree, but that's something approaching a rational view. Simply saying "it's just how people are" is a moronic justification.
