For shared housing like apartments I kind of get extremes opposite the outside temperature. I can be in my underwear (work from home for the win) still a little warm and my wife will be wearing long clothes and one of those hoodie blankets. If there were a weight differential I imagine this would only get worse. Multiply that by everyone living in a building, you're going to get some people far from the mean. Things like wearing tons of clothes in the AC and opening windows in the winter are just ways to give more granular control so it's not trying to fit everyone into one bucket. In single homes it tends towards more plain inefficient as the number of people to optimize for lowers but that leads to the next point.

In general I don't think efficiency is really a problem. It's self regulating, being more inefficient costs you more so you must find it worth it and that's your choice. The real issue is the incentive mismatch of dirty energy sources being cheaper than clean energy sources. There is nothing inherently problematic with someone deciding using 2 mWh instead of 1 mWh in a month is how they want to do things or deciding it's not worth trying to change things around to optimize.
