If you relocate a government agency HQ to an area that doesn't have any competitive jobs, you're making it more difficult for that agency to attract and retain tallent.
Just by moving the office in the first place you'll hemorrhage experienced personnel who don't want to move their lives across the country.
To proponents - that's a feature not a bug. Less effective regulation (and eventually deregulation) being the goal.
