Thanks for this, and now we are getting much closer to agreement! I would only quibble a little with the word "referee".  Referees do not design the rules of the game - they only enforce them. In the Chilean case, relatively successful, it seems that government actually designed the rules, and those rules were very strict - no ownership, only time-bound "concessions", and price controls. In addition, government supported community-based cooperatives managing water under local control in the rural areas - in recognition of the fact that private operators, being profit centres, cannot operate where profits cannot be made.
