There are already many airports without controllers, some have Flight Information Service (in Canada at least).
The pilots will have to initiate air-to-air communication and separate themselves.
Terrific move by the Feds. In IFR weather, they might have to wait for approach clearance from the En-Route facility further increasing that controller's workload, and in VFR, it can be see and be seen.
