TBH, the physical protection laws cited for 'Kinetic' are a strech at best.
It applies to citizens transiting airspace - though the definition of transiting (and of a citizen!) is broad. Most of it only applies to the FAA requiring to make policy for the protection of navigable airspace - but the definition of that is "airspace above the minimum altitudes of flight prescribed by regulations under this subpart and subpart III of this part, including airspace needed to ensure safety in the takeoff and landing of aircraft."
Caselaw in the US has placed that altitude (for practical purposes) at 500 feet (Urban), or 350 feet above any local structure (rural) - however, that could change, it is the current lower limit of the FAA in space not directly round an airport...
