> Utility is obviously the dominant factor.

Supply and demand is the dominant factor in pricing. Utility is barely quantifiable in most cases. A personal computer has immense utility, a Rolex has very limited utility. The latter is in very short supply and in high demand, that's why its prices are high.

Now let's take a software engineer at Uber versus a nurse at a random hospital. The software engineer is part of a scheme that keeps destroying capital, his utility is negative. The nurse on the other hand may prevent decades of lives lost every day. It's not that hard to become a nurse though - more people are capable and willing to do it, so the supply is large. The cherrypicked software engineer on the other hand, is quite rare.

> why wouldn't the Phoenix person have the same opportunities to switch jobs as the NYC person if both are able to work remotely?

They have the same "fully remote" options, but not the same "onsite" opportunities. If you work remote, of course you're going to want to optimize your cost of living, because you'll be competing with people who will do the job for less money.
