The notion of freedom is clearly paradoxical. If everyone is free to do whatever they want, they are free to restrict other people's freedom, and hence those people are not free. If this is not allowed, then nobody is truly free after all.
So we take a step back and change the definition of freedom to something like
to be free means to be free to do whatever one wants -- except that which affects other people's freedom
But now the definition is too general to be of any use, since anything can be interpreted as affecting other people's freedom. I mean, if you breathe air, you breathe in oxygen that I might need. YOU ARE AFFECTING MY FREEDOM BY EXISTING!
See?
So is the notion of freedom nonsensical?
