Compromising passengers safety
As a potential passenger I want an assurance from the airline that they will not deliberately expose me to life threatening hazards or theft or damage to my property.
Lithium battery fires are known events, which are not controllable in a cargo hold. Valuable possessions beyond my physical presence are subject to theft, interference and mishandling without any meaningful defense.

Ideally our benevolent big brother will know everything going on and stifle any acts of terrorism before they develop beyond mild grumbling about the poor quality of reality TV, with airport security screening to catch the ones who evade the monitoring.

This is unlikely.
Fires in modern digital equipment - Does happen.
Checked baggage broken, stolen - unavoidable.
