No, you don't get it. DRM is economically flawed because of asymmetries in power/aggregate power controlled by individuals vs. centralized organizations. DRM on behalf of individuals can work by coercing corporations into compliance by means of regulations, threats, and punishment.
The exact things that make DRM bad when used by corporations make it potentially very good when used by individuals against corporations. It is basically the same privacy vs. openness arrow between individuals vs. corporations. It's a public good for individuals to have privacy and corporations to be open and transparent. It's horrible the other way around. Likewise, it's a public good for individuals to have DRM to protect their data against corporations. It's horrible the other way around.
Also society doesn't have a point or purpose, society being basically what happens when you get a bunch of people together. And if governments have a purpose, that would be ensuring the well-being of the citizens by proper usage of force. As a society we've decided that this means protecting the rights of individuals.
But what "freedom" are you talking about exactly? We've clearly decided as a society that murdering other people or having slaves aren't freedoms worth protecting.
