Ok but for most people work hours are dictated by a shared clock (and many daily activities as well) so... It becomes a coordination problem if we don't all agree on what time it is in each locale.

I appreciate the coordination problem here, but I do think that states are making it harder than it needs to be. The federal government doesn't need to be involved. Each state can decide on their own how to coordinate this, it does not need to be the entire nation (and indeed it already isn't, as the examples of AZ and HI show).

Considering that one of the biggest problems in our country today is trying to run more and more at the federal level instead of at the state level, it's really silly to add to that pile.

No, the law is that states can decide to not implement DST at all, but they can’t decide to have it permanently.

At one point a couple New England states were looking at this, but for that reason it would have been implemented by moving to a different time zone: year round AST rather than year round EDT. (Which are both UTC-4.) That said, I think states need federal permission to move time zones, too.

The federal government constrains what states are allowed to do, so it has to be decided at the federal government. AZ and HI got legal exceptions long ago.

As I understand it, any state is welcome to keep standard time all year, as AZ and HI do, without dispensation from the federal government.

Changing time zones or keeping permanent daylight time requires a dispensation. It is my firm belief that state legislatures have voted to keep permanent daylight time as a way to not actually change anything while telling constituents that they're doing stuff.

Uniform time act of 1966 prevents this being set at the state level outside of remaining forever in standard time.

Let the market decide. If it's worth it to some people, then they'll pay for the privilege of doing so.

Right now, the revealed preference is that there is zero demand for it.

What does that mean? People pay for it to be light out at 6 PM, or we bid on what time sunset is? What does this problem look like on a market?

And by what metric is there zero demand to solve the time-change problem?

Markets don't solve coordination problems

What are you talking about? Markets solve the distribution and valuation coordination problem by price signaling. That's the whole shtick.

Markets are a heuristic for solving some computationally hard problems. Heuristics get stuck in local optima. Overcoming local optima is presumably what GP meant by coordination problem.

Obviously request a reasonable accommodation and sue if you don’t get it.
