Woah easy tiger.
I have flown in France and many other places without GPS and managed quite nicely.
I am not anti GPS in any way (got a lovely 296) but quite simply if you are flying VFR you cannot rely on GPS and nav aids all the time. GPS has dropped out a few times for no apparent reason and batteries and power leads have failed, I have been unable to use nav aids due to being in remote places and at low level due to weather (not exactly flying in airways are we?) to avoid some of the airspace you have mentioned. Guess what when everything else failed I looked out of the window picked up my map and set the stopwatch going, and never got lost.
The original post was about navigation and not use of technology I am a huge fan of GPS and use it on a regular basis but you still need to be able to navigate using conventional techniques have you ever had a GPS failure or been unable to use a navaid? It does happen!
Thats exactly why the CAA make us pass a nav test without relying on GPS and navaids!
Technology is a tool but only a tool relies (100%) on technology.
