> Should a person be charged SF prices for groceries when they're living in Atlanta because they're getting SF pay?

Your reasoning makes no sense. It's a choice to live in a city that lets landlords dictate which buildings can be built. Atlanta and other cities are unconstrained for new housing development.

SF policies are a tax on its non-homeowner residents.

You shouldn't be entitled to a differential just because your city doesn't build new housing fast enough. That has no bearing on the work your employees perform.

> You can't have your cake and eat it too.

You can if you have sufficient negotiating power.

Then, it should be fair for a person with 4 kids living in Atlanta to be paid more than someone without any kids living in SF, right? You clearly missed the entire point of the article.
