Hmm.. Maybe I am out of the loop, but what is the problem here?
So you need to ID yourself to get to certain airports - What's the big deal? Heck, I can't get into my local RSL unless I am a member!! LOL!
Are you against the cost? Or just having to ID yourself to get access to certain airports?
I don't see the problem, to be honest. I did mine online, and and with the local PO, and it was painless (yes had a cost) but was a non event! Lots of tings have a cost. Car Rego, Drivers Licence, Local Clubs, etc etc.
If the cost of your ASIC is the largest of your problem, then I reckon you have few problems. But that is just my opinion.
But again, I am not sure what the actual issue is here. 10 minutes of paperwork and a visit to the PO. I go there everyday to check my mail anyway! LOL!
