Aviation has solved this problem a long time ago by controlling airspace and having laws that are actually enforced. Your plane may not prevent you from entering restricted airspace, but it may very well be the last thing you do as a pilot.

Besides, modern planes have tons of automation that can take control of it, from simple things like preventing it from stalling to more complicated things like avoiding flights into terrain or automatically landing the aircraft at the nearest airfield.
