What's wrong with a moving map GPS?
Nothing, other than a pilot with some sense of self respect would want to maintain some proficiency in having a back up plan. While flying in an unfamiliar area last summer, in a GTN750/G500 equipped aircraft, the magnificent GPS and glass cockpit display actually became a distraction during lessening wx conditions, so I reverted to nav 2 to intercept and follow the localizer. The simple way worked best, with the moving map simply for situational awareness.
To the OP, yes, using two VOR radials is great for confirming your position. Time is a very useful tool for knowing where you are, or at least where you could be. Most important, if you are in, or near controlled airspace, and you could be lost, tell ATC without delay. They will not laugh at you, they will help....
