Ostrom's work is parochial. Her real-life examples center on small populations adjacent to large natural resources with access negotiated via long-standing community mores. That simply doesn't apply to the high-density populations urban environment where most of humanity lives, and where community ties have less sway. In these situations where most interactions are transactional a robust and fair regime of property rights is probably the ideal solution. With property rights the transaction costs are borne by the property owner up front, while in the community-based the transaction costs are encoded in tradition and personal relationships.
