Problem: High prices not diminishing demand - example: 'peak oil myth' - so oil prices are going up, which means people will use less, and alternative forms of energy will become viable. Ok I get that. But what if, despite the high prices, a select group of people is willing to pay until it's gone? A more applicable example of this happening might be a certain kind of animal meat - say some rare, exotic species. Super rich people might not care if it's going extinct and still want to buy it to the very end. How can this be reconciled without legislation prohibiting it - is there a free market alternative?
