I always find amazing the way people tend to appropriate things. Moon and Mars (it belongs to yemenite I saw somewhere: Three men from Yemen sue NASA for trespassing on Mars) offer a nice potential :Lunar Embassy and its bank Lunar Embassy Bank or Lunar Republic Society... all wants to sell parts of the moon or even mars/venus... private companies "ne recule devant rien" as we say in french !

HOWEVER: as stated by the Moon Treaty:

All activities on the moon, including its exploration and use, shall be carried out in accordance with international law, in particular the Charter of the United Nations, and taking into account the Declaration on Principles of International Law concerning Friendly Relations and Co-operation among States in accordance with the Charter of the United Nations, adopted by the General Assembly on 24 October 1970, in the interest of maintaining international peace and security and promoting international co-operation and mutual understanding, and with due regard to the corresponding interests of all other States Parties.
