The problem is literally built into the lore.
From the official lore bible https://devblog.dualthegame.com/2016/11/16/official-lore-bible/
"One of the key functions of the ship once arrived, is to deploy a 20km radius safe zone area where colonist would be free from any form of aggression from the outside, or… from themselves. It was indeed decided that the potentially violent nature of mankind under stressful situations should be mitigated with appropriate supervision. Within the safe zone, Aphelia is in charge of maintaining order, and providing support and information to colonists."
