I get that there've been studies about this so it's hard for me to argue, but I still can't quite understand how it has such a strong effect. If someone happens to be busy one night and goes to sleep an hour later than usual it doesn't seem like the end of the world to me.

I think it’s like jet lag. We have our own natural time and sleep rhythms. If you go to bed late yes your tired the next day, but your time sleep rhythm is not affected, your body knows it is short of sleep. When someone messes with the clock your body is out of sync for a number of days.

Multiply the small effects you can imagine by about a billion. Even small disturbances have an impact at this scale.

at this scale

At what scale? It's losing an hour of sleep, which people who aren't terribly overworked or on super tight schedules should be able to handle without much issue. I still don't really see the difference between losing a single hour of sleep one day and moving clocks.
