Is Lake Mobius A Punishment?

Got that itch again and been watching a bunch of videos on different theories and had a random thought. We know that humanity came from the DC, or at least it's heavily implied, but most talk about humanity fleeing from it. What if they were sent into Lake Mobius as a punishment? Having a gatekeeper and needing a guide feels like what you'd do to keep something confined and only allow certain people to leave. The calamaties being a punishment for going there makes sense if it's a punishment for trying to return after being banished. Just a random thought and was curious what others thought. I know it's not super thought out.
