How far can anyone really deconstruct anything before it becomes meaningless anyway? Sure a picture is made of pixels. Many, many of them in a photograph I can take on my digital camera. What good does it do to see the single pixels?- they make sense as a whole.
I like freedom. I wouldn't want others to intrude severely on my freedom. One way to try and influence others to not oppress me is to try not to oppress others. Of course, however, my idea of the freedom I am entitled to is shaped/formed by my knowledge of the world around me, and the social norms. I suppose you could come up with a social order in which the oppressed expect to be so- and in many historical contexts, this has been true.
Do people need freedom? I guess maybe it's tied to survival. You want the materials to survive- food, clothing, shelter, etc. And as people get more technologically advanced to get these things, freedom becomes somewhat an mix of those same urges/goals? Will think it over some more.
