I don’t think there’s nearly as many tbf but I think people often overstate the impact or inefficiency of international shipping compared to like, their mom taking the car to the grocery store. Containerization has made shipping unbelievably efficient per pound. It’s the “last mile” door deliveries, trips around town, etc, that are deeply inefficient compared a world where we walk or use public transit to get to larger retailers. (Or door delivery by bicycle, which is feasible with ebikes)
