Suppose you are navigating solely by GPS. What are you going to do in
the event the military chooses to disable the GPS system while you're
airborne (or a solar storm renders GPS unusable) and you find yourself
above an undercast? If the aircraft isn't equipped with ADF, and you
haven't been trained to use VOR navigation, you'd have to request a DF
steer from FSS, or if you're located in an area of ATC radar coverage,
vectors.

And if the sun suddenly went supernova, I'd be in big trouble, too.

Why do I suspect that the old A/N radio range pilots were saying the same
thing back in the '50s, when the Feds started decommissioning them?
