You have a warped definition of slavery, surely.
Living in a society, you have to compete for stuff which that same society produces. Goods. Services. Status.

Reality: men are NOT free in absolute sense no matter where they live or who they are. Whether it be in the woods or developed human society with it's greedy corporations and banks -- there are constraints everywhere. Out in the wild, you would not be free to go over there because it's grizzly bear's territory, and you would get torn to pieces. You also would not be free to access goods and services people produce. You would not be free to post on the internet. Or eat tasty food which you can't catch/grow/cook yourself. Or wear decent cloth. The list goes on.

You are free to become a hermit if you feel it would give you the freedom you desire so much.
