First off, welcome to the forum! You’re definitely in the right place.
Definitely check out The Ultimate Beginner meta-thread for a comprehensive collection of relevant links and threads. I think you’ll find it really useful. (Also be sure to check out the welcome link there for forum tips and how-to’s)
As for your question, jdk pretty much hit it. Check out some of those resources in the meta-thread to help get a better understanding. I recommend “What Libertarianism Is” and the “Law Without Government” series by our own Graham Wright.
