Previously, if you headed up a tech firm in Wyoming, for example, your talent pool was the set of all the residents in Wyoming. You'd struggle to retain your top-end talent and you probably had to overpay to get them to stick around. Even worse, you probably had to donate to the University of Wyoming (read: bribe) to get them to train their students the way you needed them trained.
With remote work, you just scribble out a post on Indeed, wait a week, and then pick the most desperate candidate that has the qualifications you need. If they threaten to leave, you offer a token raise knowing that you could always find someone else if you need.
