DNS, unfortunately 'who will be paying' is a fact of life; left to us by the great benefactor. Free in G, manual telephone exchanges and dirt-road airspace come to mind. We then progress to a time when we had a malleable, idiot transport minister, who couldn't find his ass with both hands. Subsequently we got NAS - Swahili for 'gigantic f*ck up.'
That's done. The real issue, in the contemporary environment that we've been stuck with, involves accepting the current mad-woman's breakfast, accepting that we have to pay, but asking why we should agree to a dog of a system when we can have guaranteed separation between IFR and VFR for the same cost?
