I can't answer your question w/r/t Security rules, but I can tell you that ORD is an airport where your "idea" simply wouldn't work. Can't get from inbound airside to outbound airside without going thru C&I. Additionally, once past C&I you could just as easily hop a cab downtown.
I think the upthread post regarding the fact that some/many of our airports don't have the neccesary design features is answer enough.
