Those are some good arguments, though from my perspective it seems like it could be simpler.

For one, just like you can't get up early, some of us can't sleep in. Takes no effort for me to build up a habit of waking up early, my body just likes to wake up at 4:30AM. I go to bed relatively early because I'm going to be awake at 4:30AM either way so I might as well try to make a full night of sleep happen.

Other than that, I think there might be a bit of moral judgement going on, but I think it's just that the business day starts at 8:00AM and sleeping past that looks like lazy or luxury. One thing I like about working in tech is that there is less judgement there -- hell, if anything, I get more flack for waking up at the crack of dawn than my coworkers who get into the office at 10:30AM or 11:00. I'm not the only guy who gets into the office early but on my team I'm in the minority.
