I read a sci-fi book once about a libertarian colony on the moon. They rebelled against earth, I think. What is the name or title?
A likely book that fits this description, is The Moon is a Harsh Mistress by Robert Heinlein, 1966. There are multiple memorable parts, including the aphorisms "it's no more free than the air you breathe" and "TANSTAAFL".
As for the rebellion, it turns out that rock throwing from the top of a gravity well is... effective.
