Oh come on -- You can't
still believe that drivel, can you? Of course this has to do with revenue protection. The airlines will never admit that, but they are all too happy to let the TSA enforce this provision of their ticketing policies.
Regarding having a legitimate purpose to enter the secure area, the ID check does nothing. I could be at the airport to steal wallets yet as long as I purchase a refundable ticket or get an airline to issue me a gate pass I can enter the secure area.
