While citizens have a right to transit through navigable airspace, the FAA controls more than that. The FAA controls ALL airspace (but delegating control over some areas such as military airspace).
For example, a drone weighing over 250 grams must be registered with the FAA, no matter what height it is flown. Even if it's your own backyard at eye level.

This is a little weird, but factual.
