(again, from what I'm aware) Dense materials might not be ideal for insulation, but their density makes them pretty good at thermal mass, so their uselessness at insulating would be moot because the end-result is similar enough to insulation regardless of r-value. They store mid-day heat well into the night and they store midnight coolness well into the day. Cob houses have no insulation, but the mass of the walls means that with proper airflow designs, passive heating and cooling is possible. Though it really does depend on the climate of these kinds of buildings to be effective, otherwise insulation is definitely the way to go.
