They already change schedules though, we just launder it through the time “change” despite clear evidence of costs in both productivity and literal human life.

> They already change schedules though

Yes, because the rest of society also changes their schedules, in sync. Most people don't have the ability to unilaterally change when they work irrespective of everyone else. If they did, switching between DST and standard time wouldn't matter either—just tell your boss you'll be coming into work an hour "later" in the summer.

Clubs and churches will be based on when people can most likely make it. I think those things will sort themselves out. They already accomodate for things like weather, light, etc.
