The big problem with solutions of the pattern "allow the tragedy of the commons to take effect and leave the solution to the natural learning curve" is the uncomfortable interim between the problem appearing and the market adapting. I wouldn't mind as much if it only took a few weeks to convert an office building into a parking garage, or a few years to pull excess carbon dioxide and methane out of the atmosphere.

Why not make all prices reflect the actual cost of goods through their entire lifecycle, from creation to disposal? Right now, I pay a flat fee for getting rid of garbage; the only bonus for bothering to separate things for recycling is to my conscience. This general "throw anything away, it's OK" policy constitutes a subsidy to people creating goods that have no plan for end-of-life beyond "be part of landfill until someone figures there's enough valuable stuff in there to mine it".
