A valid point of view, of course. But Pecos could be an interim distribution point where IMG does two things: do something for their cardamine dependancy and prepares to move them to a safer and more habitable place of their choice.
I'm sure most would settle down on Yuma alright, but definitely not all of them are eager to forcefully become Crayter citizens.
Overall though, the event idea's great and breathes much needed life into Taus that isn't traders aggressively printing money on currently most profitable route. One I'll try my best to show up for.
