Sure I want, why I wouldnt? >: Why to bother carrier at all with all stuff on board.
What is the principial difference going there and going back? Same uses for carrier.
If someone wanted to head out into the black and leave the bubble behind forever, Tritium availability is the only limiting factor at the moment. Exploration and UC installed will more than cover upkeep and paying for people to deliver Tritium to you (if that works). Also UC being there means that you don't end up flying around with billions of exploration data, risking it every time you jump into a close binary system.
Additionally, having all your other ships with you means that you can do whatever else that you want (ok, apart from trading and combat, but even then if you had others on board you can combat amongst yourselves).
In order to be able to do any of that, a carrier is extremely useful and the bubble is not necessary. So yeah, I can easily see that some people will not want to come back, or at least spend years out there.
So the main difference between going there and going back is that going there is open-ended, but going back is probably based on need (for Tritium).
