How do you define "freedom"? I define "freedom" as the ability to control
your own life. Copyright does not control your own life. It controls others'
lives. That's power, not freedom.
You seem to be attached to the idea that copyright is property. This isn't
the case. Copyright is a legal monopoly system established a few centuries
ago as an industrial regulation. It's completely unrelated to property
rights. The reason theft is illegal is because something is taken away from
someone else. If you steal a bike, the owner of the bike doesn't have it
anymore. Copyright infringement doesn't do that. It's more like creating
magical copies of bikes and giving them away, affecting the business of
selling bikes.
