> Do you imagine that people who commute by bicycle or train are going to carry around durable versions of every single-use item they currently encounter? Cups, straws, plates, utensils, napkins, takeout containers, grocery bags, produce bags, tissues? Carrying around dirty versions of all the above until they get home to clean them? Doesn't seem uncommon at all to me, that's what my colleagues and I do, same for my wife and her colleagues (and we work in very different environments and places, different countries even). Some of my colleagues wash their dishes at work, I just bring them back and put them in my dishwasher a home. My wife has a dishwasher at work so they just put their stuff there. The products we use for washing at home or at work claim to be biodegradable and not harmful for the environment. Properly taxing externalities is an obvious thing to do though of course.
