This argument as framed doesn’t make any sense. Porn is (and WAS) Internet 1.0.

There was porn before most everything on the web. Porn is also speech / art.

Anonymous access should be available for any website that wants to share their content on the Internet provided they have the rights to that content.

States that seek to limit that could make a legal argument that they have the right to limit access, but in the end it’s infringing speech. Worse, it’s unenforceable.

And yes, I would make the same arguments for people posting hateful shit or misinformation.
