The delay was actually because the Range hadn't approved the Flight Termination System on board F9. The Range is really not the gatekeeper for orbit, their job is to protect the public and ensure that the rocket doesn't harm the uninvolved public. Thus the sea lane closures, airspace clearance, clearing of the immediate area, and FTS in case the rocket deviates from it's proper course (within margins, of course).
