Max, Give me a phone call on 0418 640 221 and I will explain to the best of my abilities how the US and Canadian systems work.
In both of those countries ATC provides an excellent LSA/MSA alerting service when in radar covered en- route airspace.
It works because there is a disciplined system to report when visual or cancelling IFR. We do not have an equivalent procedure for our en-route radar covered class G airspace and thats why you cannot understand how it could work.
Why don't we at least try the procedure at just one airport?
Or are we not as capable as the North Americans?
If it requires the employment of some extra ATC's so be it- we are a wealthy country and value human life at a similar value to that in North America.
And the alarm system you describe is rediculous and exists because you have to provide a 1950's Flight Service type information service rarther than a proven NAS type service.
Why don't you contact a US low level en-route controller and ask how it works?
