Yea, anti-circumvention law violates the idea that consenting adults should be allowed to do whatever they want in the privacy of their own home. I wonder what will happen to patents if 3D printers become more versatile and as common as 2D printers so common people can download items from online? The download surely won't be patent protected, and the end user might be able to legally print it under the "experimental use" exception.
