As far as managing different groups of people this can be addressed with the implementation of communities using hivemind but you are probably right if we consider that value distribution using a single token can be problematic if one community has way more stake than another one. I still think that we need another vehicle to distribute steem to as many hands as possible other than just with block rewards and "interest". Maybe we can reduce the rewards pool to a minimum and just allocated to steem related content.
