Fine. Under the libertarian platform a person can sign a contract or refuse to sign a contract. That is the person's liberty to do as he or she chooses. The person didn't lack liberty. Your argument is refuted and you even supplied the definition to refute it.
I don't trust you not to make up your own mutations so just provide the quote and URL from the Libertarian platform that supports your argument that perpetual servitude is consistent with the Libertarian platform.
