Currawong whilst you make a good point I would say it is aimed more at the Al Quieda pilot...
After all how many pax could take over and fly your aircraft into a building?
But how many crim checks do you need? ASIC card, Lic, truck Lic, fork lift Lic. Bit like the medical need one for flying, one for life insurance, one to race cars..... Why can't they all be done at once?
Even so the user pays system is on the way in every bloody aspect of life...
