If only there were some way that someone could find prohibited items in luggage and remove them... some sort of administration for transportation security or something
Only loose lithium batteries are prohibited, and security takes them out just like they take out gas cylinders for camp stoves, fireworks, huge magnets, etc.
The real punishment for forgetting to put phones in airplane mode is that you arrive with a flat battery. Just barely getting a signal and immediately losing it, over and over, takes a lot of energy.
