Liberty and freedom are not the same things. Liberty is when you have choices and options. Freedom is a state of being on the inside. You can have liberty and not be free (for example if you are struggling with an addiction). You can have your liberty taken away (by being locked up) and still be free (because no one can take your internal being away). No one can control what you think, how you feel, and how you decide to react. I can keep my sense of self intact in spite of what is going on externally. Freedom is a state of mind while liberty is an environmental state.
