> Your body's internal clock is actually 24 hours 11 minutes long on average
Wasn't that debunked? Just look at what happened to people who slept in a cave for a few days, they came out of it having no idea of how long they were in there, even if they were somehow conditioned by others who guessed their own time. If the body had an internal clock, their estimation would not be off by 17 days out of 40. That's some serious mismatch.
I really don't get what you're saying. Move the clock 4 hours forward and you favor some people; Move it backwards and you favor others. You literally cannot make everyone live in their "perfect sleep cycle." If you feel sleepy "at 2am" this changes nothing for you.
In Norway in December people wake up "in the middle of the night" because sunrise is at 10am: Humans can adjust easily to this stuff, it's just that we like to sleep "late" (as defined by the clock)
