This is a useful measure to point the law as a weapon against drone operators who may be recording what’s going on by accident or on purpose. Any drone made in the last few years is going to be emitting its ID, which likely has been registered with the pilot’s name and contact information.

They can then after the fact come down on that person without having to get facial recognition, grab cellphone beacons, or other similar steps.

It's trivial to build your own drone without a DroneID.
