Ok. I think I understand.
I think the ideological obstacle for me to agree, though, is that the small-scale democracy model shares most (maybe all) of the same qualities that you're talking about.
The group, as a whole, decides what to plant, where to plant it, and who will tend to it. Only after that model reached a level of sustainability did the shift to private ownership even make sense.
Those competing human characteristics - greater good and desire for freedom - are what Marx described in his work. There is a fundamental tension there.
It is also why (IMHO) the movement toward socialism is so slow. So far, it hasn't appropriately struck that balance. People always want to be free. They only work together when there's a clear benefit to doing so.
Historically, socialism has not been able to establish any real upside.
Right. For socialism to work, it requires people to set aside their competing self interests. I must work for the greater good. I must surrender my desire to enjoy the fruits of my labor so that others that have failed (or failed to sufficiently try) can have them instead. But human nature always gets in the way.
