Anarcho-capitalism is a system where there is no government and people get to decide what's fair and what isn't fair. Instead of a government making all the decisions, people would be able to make their own choices about what's fair and what isn't. This means people would be able to buy and sell things with each other and businesses could offer services to people. It also means that people would have the freedom to choose what kind of laws they want to live by, as long as it doesn't hurt anyone else.
