Alright kiddo, let's talk about libertarianism, but first let me explain what "metaphysics" means.
Metaphysics is a branch of philosophy that deals with abstract concepts like space, time, and existence. It helps us understand the fundamental nature of the world around us.
Now, on to libertarianism.
Libertarianism is a political philosophy that believes in individual freedom and minimal government intervention in people's lives.
Imagine you have a toy that you really like to play with. As long as you are not hurting anyone with it, you should be able to play with it however you like. This is one of the basic ideas of libertarianism - as long as you are not hurting anyone, you should be able to do what you want with your own life and property.
Libertarians believe that people should have the right to make their own choices, rather than the government making choices for them. This includes things like whom they marry, what they consume, and how they spend their money.
They also believe that the government should have a very limited role in society. This means that they only believe in having the government provide certain services, like protecting its citizens and enforcing laws, but not in controlling people's individual lives.
So, to sum it up, libertarianism is all about personal freedom, individual choice, and limited government intervention.
