The problem is that whether you're an "early bird" or "night owl" is a matter of biology, not how early or late you choose to wake up (https://www.livescience.com/16334-night-owls-early-birds-sleep-cycles.html https://www.livescience.com/16334-night-owls-early-birds-sle...). Because of the way school and work schedules are structured, you're right that it can give you an edge to be a morning person (I'm fortunate enough to be one). However, waking up early doesn't make a night owl an early bird - it makes them tired. The fact that people are split along these lines makes it questionable to enforce schedules that suit part of the population but leave the remainder strained and underutilized.
