Plus, "solar noon" itself shifts by ~20 mins throughout the year due to the Earth's orbit.
With standard time you will still have the rough center of the time zone match with solar time with about +/- 30 minutes give or take on the sides. With DST it may well happen that no part of the timezone actually matches solar time since everything is essentially shifted 1 hour to the East.
Sure, it's easy to say "just leave work an hour earlier" and some people have that flexibility. But far from most, I'd wager.
I'd love to live in a world where bankers and dentists and optometrists all kept different hours, so the bankers could get glasses, and the dentists take out loans, without having to drop everything to do it. With smart phones this is somewhat more tenable. I don't need to memorize when the dentist is open, so there is less immediate value in reducing the world to a small set of common numbers.
That’s where the problem is.
The real Sun and the imaginary “mean Sun,” from which mean solar time is measured, may be as much as 16 minutes apart because during the course of the year the apparent motion of the real Sun against the background of the stars (the ecliptic) alternately slows down and speeds up.

The east–west component [of the analemma] results from the nonuniform rate of change of the Sun's right ascension, governed by combined effects of Earth's axial tilt and orbital eccentricity.
Then you must not like time zones, as that is true only in one particular sliver of a time zone. You want true local time, like before the railroads time.

For me, personally, I like the concept that noon is when the sun is at it highest point or closest, I can adjust everything else around that.
