Dick, you are arguing against radio usage rules you don't understand, which is why you keep using scaremongering scenarios that don't exist.
All those pilots in aircraft at all those little unmarked strips on the 'J' curve and mustering cattle in the outback who would cause aluminium confetti aren't blabbing on the Area frequency.
They are not blabbing on the Area frequency for a reason.
The reason is not because they've decided to 'defy' the 'CASA ruling'.
It's because they don't have to blab on any frequency.
There are no mandatory calls at unmarked, unregistered, unlicensed strips in G.
The cattle musterers at Upper Bollogworlldarga are monitoring Area and blabbing on their own chat frequency, confident in the knowledge that they are the only aircraft at 500' within 500 nautical miles.
The aircraft departing an unmarked strip in the Southern Highlands of NSW might, if radio equipped, make a "rolling at / for" call, on Area. However, they are few and far between. And they still get a choice.
CASA is going to make you look very silly.
(BTW - I agree with the point that RPT Ops into places like Ballina in ForG make a complete nonsense out of any comparative risk-based objection to E.)
