I believe that it is as i stated above but also this
It is our right to be treated fairly and evenly, as in equality.
For example if I go into a situation and someone decided to treat me unfairly, or to cause me to have to deal with extra problems, do extra work or basically acts in a way that is detrimental to my quality of life.
We can then say that I am a slave to their desires or selfish needs. Or if I am paid far less than I should be for something or when doing something, then again I become a slave to the will of others.
So the limits of individual freedom can be measured in the amount of choice we have but also in how I am treated and how that treatment by others affects my quality of life and mental state!
