> If it's not online why do you need security updates?

For the times I need to download packages ?

Besides, better ask now than to start with it when I need to access the
internet yesterday.

> Where's the attack vector for an air-gapped system?

USB devices (thumbdrives, keyboards, etc) ?    NOOBS or other ways to
install an OS ?  Packages ?   Bluetooth ?  Wifi ?    Poisonned resource
files (images, music, video, spreadsheets) ? Booby-trapped source-code ?

Air-gapping isn't the ends-all defence against intrusions you know. :-)
