You’re not wrong, but hoping people will choose anything other than the default thing is going to result in failure. If you lay out cities for cars, people will use cars. If you build massive urban areas in places that stay in the 90s with high humidity, people are going to blast the AC. If disposable things are cheaper than longer lasting things because there’s no cost to throwing it away, people are going to do it.

People just follow the path of least resistance in a given environment and only an extreme minority are ever going to be persuadable to consciously go against that at all. If we want different behavior, we’d need to bulldoze most of America and start over.
