How are you limited? What is the limitation? If the mafia and the State and the Noble Lord assume rights that you don't like, what is the consequence? Promises are empty until they are actually performed. So if liberty depends on agreements, what is the consequence for someone who refuses to keep his promise to abide by those agreements? And who enforces that consequence? Is enforcement up to the wronged individual? Even if nobody else thinks they were wronged? And what mechanism of enforcement exists besides physical restraint or physical harm? And who comes up with the agreements defined as "liberty" in the first place? And how do you know someone has agreed to them so you can have some basis for confidence in dealing with them?
