Yes, the core problem is the law. But until the law is fixed, I'll take issue with something that extends the application of the law.

And I think it does get to the essence of it, because of just how we quantify something as illegal. The laws are very poorly written, where the worse images possible are treated just as no more illegal than images that are on the borderline of legal (not to mention that the border itself is very fluid, especially when considering artistic images that would be illegal if they weren't artistic but which is left up to a random jury to make a judgment call on).
