The the school, and every employer, and every government agency, and the stores, and the public transportation, and so on and so forth.... will have to all agree to change their hours. On the same day!

You might not like DST, but leaving it in the hands of every entity to interpret is a far worse situation.

> will have to all agree to change their hours. On the same day!

Imagine if there was a powerful body representing the population that could decree a change like this!

Instead, we only have a body powerful enough to decree that all of those people change their clocks on the same day.

Anyway, the best part of changing the hours instead of the clock is that not everybody needs to do it on the same day.

> That's why DST is an abomination which must be abolished.

Don't scapegoat it too much: The underlying problem of time-shifts will still exist, and that edge-case still needs to be handled by other means.

DST just makes shifts more frequent and obvious. One might even say that it draws an important amount of attention to a broader class of problems.

That's a much less simple solution at the societal level, which is why it probably won't ever happen.

Time zones are an abomination. It’s UTC or bust /s (or not?)

Even UTC has leap-seconds. You could go a step further to TAI which is pretty stable unless some phenomenon starts changing the rate at which Cesium atoms vibrate.
