I'm not sure what your first problem is. Are you implying that hijacking would NOT increase? Statistically speaking there have been more US hijackings before 9/11 than after. Couple that with "we are making it easier for bad guys to bring weapons on board" I think it is a reasonable assumption to say "it will PROBABLY increase hijacking" Didn't the author actually that that terrorists attacks ARE a zerosum game? (There was evidence, but the author admitted it was more anecdotal than proof) I don't think he was subtle here at all. If we ONLY had passwords because of phishing attacks, then it wouldn't be stupid to get rid of them (based on your statement) But we have passwords for other reasons. We don't have TSA for other reasons (well some people think we do, that is to find drugs)
