If we eliminated day light savings time you would still have post work sunlight in the winter.
Western edges of timezones often favor/prefer year-round "daylight time" because that's closer to their natural noon as US timezones especially heavily favor natural noon on the eastern border.
So...fix the problem at the source by changing the boundaries so solar noon is clock noon at (approximately) the center of the zone instead of the eastern boundary.
Before the railways every city and/or county just about was its own time zone and a lot of the historical records are in major computer timezone databases if you feel like exploring them. It's fascinating. (Including sometimes minute and second offsets from UTC; things that programmers sometimes wrongly assume aren't possible with UTC offsets.) I think it also should also be somewhat obvious pretty quickly that it is a communication nightmare for any company with a presence in multiple cities or any person travelling between cities.
I also think "Swatch beats" made it seem pretty obvious to me that no one actually wants to standardize only on a single timezone with no offsets either.
You're right. Also no one wants 28 day months either.
My own ridiculous reaction was trying to use the French Revolutionary Calendar with the English month names (either the joke ones or the more serious proposal depending on my mood): https://en.wikipedia.org/wiki/French_Republican_calendar
It's really hard to use a different calendar, even as a joke. Obviously this effort was not helped that though there is plenty of software calendars that can convert to/from the French Revolutionary Calendar quite obviously none of them were English localized (in either the witty or the serious names), and it isn't really worth the time to do that, especially just as a joke. (Today is 21 Sneezy or 21 Fogarious, if you were curious.)
And if they have an after school activity, they have to come home in the dark anyway.
It's a red herring.
Then we move school start times to what's biologically optimal for kids instead of what optimizes budgets.
By doing it this way, we keep things in synch, like business hours matching school hours matching transit timetables and so on. If every one of them changed their hours separately, we'd have a much greater mess than the less-bad current approach to daylight time.
Whether we want the functionality at all (to adjust human activities based on sunlight hours) is a separate question. Given that we do, DST is a useful abstraction compared to going without it.
