Fine if he only wants to go to Stow Maries, are you going to give directions for all the other airfields in the country?
I would certainly agree with keeping nav skills sharp, but some are not good at it and others would rather not have the hassle of planning on a chart, battling through all the notams that tell you about problems in remote areas of the world and then going elsewhere for the weather. It really is horses for courses and if you want to stick to a paper chart that is fine, but don't be so anti others not wanting to do so!
