If we abolish time zones, I’d like the option to choose if my day goes by “solar time” or just stick with whatever is most convenient for say a group of people

If we abolish time zones, I’d like the option to choose if my day goes by “solar time” or just stick with whatever is most convenient for say a group of people working elsewhere on the planet/solar system. I think the article is way too negative about something that’s easily solvable with no more effort than what is required today to keep track of someone’s time zone and DST.
