Air gapping is often "good enough" protection for all but the most sensitive and desirable targets, even if people plug things into them all the time. An air-gapped PC might get a virus that way, which could be damaging in some way, but it's not something that most companies need to worry about.
A counter-example is something like Stuxnet; that likely leapt an air gap, but it was exquisitely targeted for that scenario. I'd worry about this as a nuclear component manufacturer.

I bet the NSA would have more trouble hacking it than a fully up to date install of <modern OS> that is on the Internet. It's very possible the biggest threat vector is leaving the door unlocked.

It's too dimensional. There are too many unforeseen interactions and complications with computers and the humans in the organizations that run them. Even leaving aside moles[0] people trust to easily and often have interests that are odds with their organization. [0] Which, why should we? The world has moles.
