If DST was abolished instead of made permanent, what is your plan to make everyone (including businesses, events, transport time tables...) move their hours by one hour earlier?
Making DST permanent "just" requires a singular change of legislation, and basically never switching the clocks back to "normal" time.
As has already been stated twice in a sibling discussion here, "changing an entire culture is hard", but I'm honestly interested in hearing your approach.
How could having every business and school change their hours twice a year as they please be easier than just agreeing on couple of dates and switching everything? Instead of one time zone every thousand miles or so, you're talking about effectively having several time zones per block. That doesn't sound sane to me.
Doesn't everybody already have different schedules? Aren't seasonal schedules already a thing? Just communicate better. You can already find things like updated opening times in Google maps, etc.
"Just communicate better" puts an enormous burden on people. I already know the opening times for places I go regularly. Seasonal schedules are not a thing here, presumably because of DST.
It's ridiculous to suggest that it's easider for every business update Google (and Yelp and everything else) twice yearly, and that everybody check that before they go anywhere. That is way more human labor than daylight savings.
Did you notice that you picked the one point you thought you could snipe at, but ignored the rest? Because I sure did. That's the sign of a bad interlocutor.
Why again does people want clock time not to match solar time? It's far more sane to change the numbers on the schedule than to change the clock.
