Very easy answer: Because it's already painful twice a year, and that would be making it even worse.
That answer is similar to the one for questions like "why do we have wide time zones that are somewhat inaccurate, rather than setting every clock based on the exact position of that clock?".
While this feels would be a disaster for other reasons like: “How many seconds are in an hour?” -> “Depends, no one knows.” … that’s already the case with our existing leap seconds.
Which we are also in the process of getting rid of.
To that end, I'd like to propose 12 transitions. These should happen on the 16th day of every month, at precisely 05:14:33.
Let's take our seasonality more seriously.
Have a look at the sunset/sunrise graph for northern parts of the US https://www.timeanddate.com/sun/usa/seattle
In Seattle, without DST, sunrise happens at 4:11am. Because of DST, it's pushed back an hour later to a more reasonable 5:11am.
I am not awake at 4am, I have no use for sunlight at 4am, and I don't want the sun appearing that early. That hour of early sunlight is wasted for me. Plus with DST, the sun sets an hour later, at 9:11pm, a time I am actually awake, and I can actually go outside and use the extra sun.
With permanent DST, then in winter sunrise is at 9am in Seattle, which is far too late. I do not want to go to work in the dark, before sunrise. So I want standard time in winter, pushing sunrise earlier a more reasonable 8am.
In both situations (summer and winter), modifying the time via DST benefits me and gives me better use of sunlight.
If your issue is when work is scheduled, well businesses set their own hours, not the government.
In plenty of countries the government decides the opening hours of shops, restaurants and sometimes even offices. Labour laws and nighttime pay are coupled to the hours on the clock. Hours you can make noise is decided by government. Germany has the mid-day resting hour (Mittagsruhe).

Ah, someone who doesn't have kids in school/camp/some random activity yet.
We know how this goes in China (one time zone, no daylight savings time). Coming home from the bar in Beijing with the sun showing up at 4 AM was quaint back then, but I'm definitely glad we have DST in the states.
I think the talk of daylight savings time is a distraction, in the end it is arbitrary what the clock says. As a society we need to negotiate when (in celestial time) we want to do certain activities. For example, there are a lot of studies that school starts to early (relative to sunrise and the average bed time of teenagers). But the school starting time has to be decided politically. And reduced working hours or later start times have to be negotiated by trade unions, politics etc.. That's a lot more messy than just shifting wall time.
I will fight tooth and nail against attempts to take one hour of daylight from me in the evenings for half of the year.
Parts of Vermont have traditionally coped with this by having an 8-4 workday instead of 9-5.
But the reality is that Vermont gets only about an hour of daylight outside working hours, depending on local customs. People have extremely strong preferences about how that hour gets split up.
> I am not awake at 4am, I have no use for sunlight at 4am
Most people aren’t awake at 5am either. Your use for the sun when there is an excess of it that goes well past your bedtime if you get up at 5am is irrelevant.
Under DST, at summer solstice, the sun rises around 5am, giving me 2 hours of wasted sunlight.
Without DST, at summer solstice, the sun rises around 4am, giving me 3 hours of wasted sunlight.
I enjoy having additional hours of sunlight when I am awake, so for me I actually prefer having DST vs without it.
Similarly, in the wintertime, under permanent DST, sunrise is around 9am, and I don't want to drive to work in the dark.
It's not like without DST you have to work so late that you don't have enough hours for sleep, right?
According to https://en.wikipedia.org/wiki/Daylight_saving_time_by_countr... since 2000:
Did they get several cities to participate?

Possibly another example of the old Chesterton's Fence.
Honestly, it was super stressful at the time. And DST that doesn't exist doesn't bother you in the slightest. Every day ends and flows into the next like the last. But the stress of a clock change twice a year doesn't have to happen, it's a choice.
(Sorry about your nightmare. It was easy on the systems I took care of at that time.)
For DST in particular: Even discussions where the participants manage to form something resembling a quorum to stop changing the clocks twice every year somehow manage to unilaterally get sucked into a seemingly-inescapable quagmire of differing opinions, wherein: The decision of whether to use standard time and stick with it or to stick with DST instead becomes an intractable impasse.
Accordingly, nothing ever gets done.
I have every expectation that I will be dead and buried before this issue is resolved.
That 2.6 million people are obese because of a 1h shorter change night in one Sunday a year is an extraordinary claim. I would love to understand how they got to this result.
