Additionally, it's right there in the First Amendment. The Supreme Court has said that the Constitution includes a right to anonymity in the First Amendment. The right to free speech doesn't come with an asterisk saying "only if you tell us who you are." Inherent in the right to speech is to do so anonymously.
As Justice Thomas said, even though there's no explicit discussion of anonymity in speech, the fact that many of the Federalist Papers were anonymous proves by example that the founders valued it and meant it to be included.
That is not to say there can't be exceptions to this right; obviously there are. But they are exactly that - exceptions.
