You could be right
As for the article, Mr Parkinson is not proposing anything new. I saw modelling of such a concept at Eurocontrol in the late 1990's (ATC2000 I think it was called). An American airline pilot was trying to flog a similar idea in the 90's as well called Free Flight. Neither have appeared in the real world yet. He could take his ideas to Eurocontrol and see what they say, but I presume previous iterations have been tested and dismissed for some reason or another.
