In general terms, making an idea illegal, and then making representations of that idea illegal, are going to be forever, at best to treadmill, and at worst reduce the effectiveness and reputation of law.
This is really about thought crime. If somebody can draw stick figures, and that can be illegal depending on interpretation. That's thought crime.
It's impossible to completely stamp out thought crime. Computer tools can be used to further thought crime, because they can be used for creative purposes.
If you restrict the use of creative tools, to only a trusted few, or hobble tools for everyone: you create central authority over creative tools, which has its own issues.
