Consumer drones already deal with a hostile RF environment well. Finding the frequency with the least interference, using a wide bandwidth for control, and a different one for video, and programmable signal-loss behaviour.
Cities are hugely hostile to low power transmission, especially in the 2.4 and 5ghz frequencies.
The effective range of cheap DJI "mini" drones in cities is measured in kilometres. If you get away from the city, you can double and triple your effective range.

We are not talking "interference", but an enemy actively looking for your signals and overpowering it with massive high powered RF.
Flying your drone around in a city is not the same as flying it against an opponent skilled in electronic warfare.

Most drone RC systems use FHSS. Those make them resistant to naive jamming. You can get fancy with jamming, but so can the way the FHSS works.
Drones evolve under this pressure. Dynamic frequency changes, computer vision, maneuvering (like "go up when lost signal") and many more counter measures are adopted on both sides.
