To have freedom and privacy, we need due process. If a Gov agency investigating a crime wants information, they can get a warrant. A lot of illegal activities happen over email. That doesn't mean the government can require everyone to give them access to their email so they can monitor it just in case crimes are committed. What you're advocating for is the surveillance system China has setup where the government has a back door to access every social media post, every mobile app, every security camera, etc. Any companies that don't comply (Facebook, Google, Twitter, ...) are banned. They make the same claims that you did that "it's in society's interest" for individuals to give some of their privacy and freedom because the society has a vested interest in this information.
