I can't make it any simpler than that. If you are doing an ILS, VOR or NDB the navaid is your primary reference and has to be there by regulation. The use of FMGC's for guidance in that case is a technique, but doesn't negate the requirement for the navaid.
You, and Denti in the post immediately above your's, are in direct contradiction. My vote goes with Denti.
