Bad idea. The market is supposed to process information for us. Consumers are just individuals who know what they need and what they want, but not much else. The market (if we are to believe the hype) can process enough information to make selfish actors in aggregate cooperate. So why not let the market solve it?

Consumer-responsibility is pure propaganda: in the same way “we” (collectively) drop plastic into the middle of the ocean, “we” (chiefly the corporations and their marketing departments) drop the symbolic responsibility on consumers.
