A controlled deorbit requires the use of several core systems, including those for communications, power, and avionics.

Another thing to worry about: the ISS losing control over its orientation in space. The spacecraft could start tumbling, flipping the station’s solar arrays away from the sun, taking the primary source of power with it.
