Because that's the literal definition of local noon.

That has value in any society that values precise measurements of physical observations.

A purposefully inaccurate time zone is the equivalent of changing the length of the meter to make your daily commute less distance in the winter and more distance in the summer, or to make the meterstick longer all year just so you don't have to drive as many meters every day. It's ridiculous for distance, so why do we do it with time?

Business hours are almost entirely arbitrary anyway. Change them instead.

Solar noon and local noon are different things, unfortunately.

Changing an offset isn't quite the same thing as changing the measure of a unit. Seconds, minutes and hours are not being adjusted as part of this. It would be more like starting to count from 1 metre instead of 0 metres to adjust the length of your commute.

As it happens, a sibling comment has already pointed out that people have effectively done this. The time of day you eat lunch is arbitrary. So the lunch hour in Spain is 14:00 instead of 13:00, effectively resolving the 'wrong hour' issue.

Fair enough. I was (of course?) using the term to mean 12:00pm which I think is what most people think of when thinking of 'noon'.

Most people have approximately zero reasons to care about when the sun is at it's peak in the sky. Valuing precise measurements of physical observations doesn't make any difference to that in any way I'm aware of.

The sunrise and sunset times have much larger implications on our activities, so why not optimise for those times? I get that any solution won't be optimal for everyone, but it's reasonable to try to optimise for the majority of people where you can.
