There are references for the amount of sleep needed. But no references for the (biological) inability to get to sleep before 11. That is the key question, are humans really unable to go to sleep earlier? (It certainly wasn't the case in the old days before electric lights and TV.)
I'm definitely no teenager any more, but I normally get up between 6 and 7 AM. Without an alarm clock. And I think the morning hours are the most productive for me.
