Borg Drones break down over time.
Less than a day.
This is not a discovery.
It's continually stated most weeks.
A few days without regeneration and a Borg Drone will be a nonfunctional mess.
A fully functioning Drone cut off from the collective can assimilate more drones, seize local technology, and build an alcove in a less than a small number of hours, so they don't have to worry about ever unregenerating to death or losing faith in the Collectives collective agenda.
Seven of Nine is not a fully functioning Drone, she is an embarrassing weak noncommittal husk, who is Lucky that those Alcoves where built by the colony of Drones on Voyager before Chakotay flushed them.
