To discuss your point about the Maroochy incident. I suggest you research the NAS intent a bit closer. The VFR uses see and avoid as the primary means of conflict avoidance in E. The VFR should be monitoring the appropriate frequency which happens to be in Dick's opinion the MC tower freq as it is the closest approach and departure frequency. ATC do not separate in E VFR to IFR. What you are suggesting is C airspace not E and have nullified the rest of your post.
