Dick,
GaryGnu makes an interesting point, which you appear to have ignored:
"I will give you a tip, if you want to gain the support of the professional pilots in this country ......"
Reading between the lines ... who is paying the bulk of Airservices' costs?
Answer: The Airlines
Any change is going to need their support. Why would Airservices take the side of pilots using the system for free (or for a minimal cost)?
What's in it for the Airlines if airspace is changed (down) to your configuration? Unnecessary grief and a greater workload for their pilots.
The bottom line is that the Business will provide what its main Customers want... whatever that is ... and it's probably dealt with behind closed doors.
Your only way to get what you want is to either:
(a) Convince Airservices' customers that what Dick Smith wants is what they need
(b) Remove the Business/Customer nexus
