I haven't missed it, but many pilots do, since they start relying on other
navigation methods as their primary methods regularly--especially GPS.

And you know this how?

And even if true, this is a problem how; by the non-existant huge numbers
of pilots getting lost or violating airspace other than TFR violations,
which is a separate issue?

Another point you seem to have missed is that GPS displays a map and in
VFR flight you compare what you see on the map to what you see through
the window.
