The important part of the ruling was declaring virtual kiddie porn protected under the first amendment.
And, please, enough with the cartoon strawmen. Computer graphics are capapble of infinitely more than cartoons.
SCOTUS has no right telling my town that we must allow access to porn in our libraries which the ACLU has argued for successfully. Next, we will be required to allow access to virtual kiddie porn because after all, who is harmed?
This ruling also has nothing to do with existing state obscenity laws. What was obscene in your state last week is still obscene today. It also had nothing whatsoever to do with mandating that your local library allow access to porn over their computer systems. You're making apples and oranges arguments.
