Adjusting your entire schedule (commute, job, child care, school, bedtime, alarm time, meal times) twice a year is much much more disruptive than changing your clocks twice a year.
I'd say the opposite. Adjusting the clock is more disruptive, because your schedule shifts anyway in relation to astronomical cycles. But besides that you also mess up the clock. So it's better to leave the clock alone and to adjust your schedule if you need to.

That's not what I'm talking about. I'm talking about calling into work saying you need a schedule change to work around your kid's new school schedule. Calling your daycare provider to setup a new schedule. If you take public transport, finding how the timetables will work with your new schedule. If you plan doctor's appointments in the future, you now need to take into account time of year to know when your and your kid's availabilities are. None of that happens when everyone changes their clocks.
When you mess up the clock currently no schedules need to change (except the people who are working at 2am, which is not very many).
I disagree that DST is as bad as personal rescheduling. People aren't currently having to reschedule work, school, daycare, etc, twice a year.
Yes there are some problems, but they don't end up in disagreements like "sorry, I can't let you adjust your shift" or "sorry, this daycare doesn't have those hours, you'll have to find a new daycare" or "sorry, this bus only operates at these times".
Now I'm not saying removing DST is actually that bad. We could remove DST without expecting people to reschedule everything. We would lose daylight during some periods of time, gain it in others, that's it.
I really don't understand what the fuss is about: twice a year the clocks change, mostly automatically, and sometimes i even forget it happened. You just wake up, and go about your day. Zero impact from DST. Once a year you're lucky and have one hour longer to sleep, once a year you're out of luck and get one hour less to sleep. No big deal.
Much easier than having to rethink, reschedule, and renegotiate all times at some (rondom) moment in the year.
Luckily, here in Hong Kong, we have a constant UTC offset, but my poor colleagues in Sydney interacting with London and New York have 1-hour swings relative to UTC, opposite direction from NYC and London. So, Sydney has a 2-hour relative swing one way, and 2 hours back the other way, with 6 different days a year to take into account.
My brother spent a year and a half in New Zealand, and 6 months in Russia. Our mom spends half the year in Arizona, with no DST. Between family and colleagues, I found it easier to just switch to UTC, but obviously most people don't. Even after interacting with some pretty smart people for years, some of them in London and New York still get Sydney DST wrong, often getting both the dates and directions of the swing wrong.
Ideally, we'd all just do international business in UTC, but that just seems too difficult for most people, so getting rid of DST would at least make things a bit easier. Granted, my dealing with 5+ time zones in 5+ countries every work day is a bit unusual. Poor Kiwis: most people think Wellington and Sydney are in the same time zone.
You decide on hours one time and don't do it anymore, instead of messing up the clock twice a year without end. I'd totally get rid of DST and leave the rest to those who want to handle their schedule in custom way.
