If your analogy is ATC, getting permission to takeoff/land your plane in controlled airspace _is part of_ said traffic control - there are simply much fewer factors that need considering for planes (compared to orbital rockets) so that permission can usually be given fairly quickly without much coordination. As the pace of commercial launches increases (and experimental rockets turn into proven designs) you should expect it to become a more routine exercise.
