Unlike most people (statists), I think the smaller the scale, the more workable hierarchy is (like in a family) but that as the group gets larger, decentralization works much better. Sharing, for example, works well in a family environment. EF Schumacher pointed out in "Small is Beautiful" that sharing requires a framework of love/caring/emotion to occur. One thing statists/socialists never seem to notice, though, is that sharing also assumes ownership, which is why even a small family isn't really all that socialist.
I was about to nitpick a bit, but then you did it at the end anyway. :) Very small groups, like families, can look almost "socialist" in their functioning, but they still aren't really. They're just very informal and generous with giving and sharing PROPERTY.
