Astronauts can crack, and probably will to some degree. Best send each in separate containers. Or, use robotics except when fulfilling requirements for filing land use and mining claims. This is moot anyway under the Treaty. If the Treaty is repealed, the rules for filing land entry and mining claims to celestial resources would have to be reviewed to see if robotics suffice for marking the corners.
Agreed that every crew member will need a private space -- even if it is hardly more than a cocoon -- to which they can retire, communicate with home,write,listen to music, research, etc.
