But that's the point, the only significant 'hardening' of airliners as potential targets has been by armoring the cockpit doors and the awareness of the passengers, the porno-scanners are meaningless in that regard.

And the justifications previously offered for said porno-scanners have turned out to be bogus. The plots mentioned that were disrupted were disrupted by other means such as sigint and humint. So why not continue to invest in the means and methods that work, and cut from the budget the ones that never did?
