Unless a tiny chance exists that some system in the middle is not secure. Then you have the problem of those who orient their acceptance to the "oh well" shrug, and then systemic faults get downplayed by default. (Edit: I re-read and notice 'half-baked systems': seemingly, we agree.)

Which is the core problem of masses accepting pseudo-heartly and not-brainy unacceptable figures. And again, systemic faults incarnated as administrations get downplayed by default.
