That's an interesting perspective. However, to create a technological model of what curation should look like in order to make curation "fair" to all parties and remove the "human bias", is an unrealistic goal.
The Steemit community is a community of people first and foremost, and as such its' attitudes are dynamic and alive. Trying to define rigid, universally applicable rules for how curation should be done cannot be done without stepping on somebody's toes.
Curation, guilds, balance of power - these are inherently political considerations and trying to apply a set of rules to guide, manipulate or influence the community towards one specific model of curation stifles expression. It must be allowed to evolve based on the aggregate expressions voiced in the community.
If that aggregate fails to represent the principles of individuals, be they whales, dolphins or minnows, they can take action to change that aggregate attitude or go elsewhere and start over. Before anyone decides to take their toys and go to a new sandbox they would be wise to evaluate their principles and make sure such a move is necessary, or adjust their principles if not.
