DST wouldn't be so bad if everything didn't need to be heavily synchronized alongside a 9-to-5 mentality. Time is useful for synchronization, but just the fact many people chastise night owls while applauding early birds, as well as emphasizing the "when" instead of the "how many hours did you do N" (or better: "how much N did you achieve"), puts many people who are dependent on more light to start their day in a weird spot.

That's what DST does. It forcefully yanks those people already struggling to adapt to society's wishes, forcing a pretty radical change. We have several solutions (group people based on chronotype, respect chronotypes more, limit the need for synchronized events in early mornings / late nights), but those still aren't being applied as widely as they could be.

Just the fact people are expected to drink coffee to wake up and participate in a relatively dangerous activity while still groggy (driving) indicates how little we actually think of all this.
