The linked Wikipedia page about the 1974 experiment says "some schools moved their start times later" in response. I agree that trying to get the entire population to shift everything on their schedules at the same time would be inconsistent at best. But many institutions would adjust to the seasons as they see fit. And you want to minimize the inconsistencies; people would pick different cutoffs, different shift amounts, etc. That's the whole point of why it was regulated in the first place.

And DST is demonstrably good during the summer. It lowers crime and improves mood and productivity. It's just not good in the winter, because people in northern latitudes wake up in the cold and dark. It kinda does make sense to have seasonal shifting.

So, unfortunately, the best solution in my opinion is in fact to just lie to ourselves about what time it is for half the year. AKA Daylight Saving.
