Is the moon habitat self-sustaining, or will bad things happen if it annoys the Earth governments who export food and water and stuff?
Physics provides certain tactical advantages to moon colonists. (Citing fictional evidence I know but as far as I can see the advantages are likely to be real).
You are now in control of a habitat on the moon. It has no ties to any government; its creation was funded by a wealthy philanthropist who just wants people to emigrate from Earth. The cost of doing so is within the reach of a middle-class family if they sell their home; you can therefore expect a decent number of immigrants.
What sort of government do you establish? How do you go about ruling so that your new settlement on the moon will survive and thrive?
