Why do you want to get out?

There is free food here and nice places to stay for everyone. So nobody has to hurt another person to not starve or have somewhere to live. [So food, shelter and some measure of safety are taken care of.] And nobody back home knows that you are gone because you will return to the same time and place if you ever leave. [At least that was true in the Drabwurld and from what he could tell also on the Tranquility, so why should it not be true here?]
