• physical disability: that might just get you euthanized.
• limited resources: again, I see euthanasia as a possible Borg solution.
• loneliness: ever heard of being lonely in a crowd?
• mental health: again, a malfunctioning drone would likely just get euthanized.

Some of these points assume the Borg we saw outside of Voyager, because Voyager really neutered the Borg in so many ways.

If I was accepted as a drone, it’d be fine by me. I’m so tired of worrying about everyday existence in the devolving hellscape of a world we now occupy.

But, if you have a physical disability, they don’t bother assimilating you I thought?

Alternatively: You have no distinctiveness that will augment our own, so we’re going to liquefy you and feed you to the childborgs.
