More like off base, but certainly not realistic.
That's totally off base. No pilot is going to risk his aircraft, his ticket, or his hide to fly into a drone to prove a point to a stranger.
You might find a couple of young goofs who might...
I flew small airplanes for a number of years and I can tell you that it's extremely unlikely that a pilot would see your drone or the strobe under the circumstances you describe.
You say that you were able to see it only at 100+ yards away while...
From 2000 ft, the plane wouldn't have seen your drone or had any way to know you were flying there.
The minimum safe altitude rules allow flight below 500 feet in sparsely populated areas and over open water, so what would you report the pilot for?
Sounds like you are wanting to fight against physics.
Just as your car can't stop on a dime when you are cruising at 60 mph, the Mavic 4 pro will take some distance to come to a stop.
The faster it's flying, the greater distance it will need...
