This is a bit absurd. First Amendment to the Constitution guarantees your right to publish papers. But now you also want the right to prevent your publications from being read? The government has had a program collecting a vast majority of publications for a very long time i.e. the Library of Congress, so one might say the precedent has already been set.

Social media accounts have plenty of private messages going on. The Library of Congress doesn't store a copy of every citizen's mail.
