So Air Traffic will shut down everything in reasonable distance of the
aircrafts routing until such time it lands its destination or a call is
received from the pilot saying he is on the ground after landing in vmc
conditions?


If it is nonradar, yes.



If this is the case (which I really hope it is) why are we taught that, in
the event of lost comms we are supposed to commence an approach at the ETA
or EFC time?


I think it's just for the sake of tradition.
