ELI5: Can you own land on the moon? Could a nation form on Mars?

What laws get in the way of these things?  I know that no nation can claim the moon, but is private ownership restricted, and if not, how does that play into activities such as the mining of the moon?

Right now all of space is more or less agreed to be neutral territory. Whenever the day comes that someone starts forming permanent colonies on extra-terrestrial bodies, there will likely be a very serious and very important global discussion on how ownership of these bodies will work. Right now there is no clear plan in place.
