&gt; I donno, I thought I made a (rather far fetched) case for when it&#x27;s actually physically cheaper &#x2F; more efficient &#x2F; beneficial to have DRM, for all parties involved. I.e. a case where we&#x27;d actually want to have DRM, I&#x27;m not sure how it relates to copyright by itself.<p>Your argument seems to be that the seller is only going to go to the effort of designing the extra feature if they can charge a premium for it to the market segment that wants it. That is the traditional argument in favor of copyright (and patents). Those things do what you&#x27;re asking for without a separate law prohibiting circumvention of DRM. The seller can copyright the enabling software or patent the feature (depending on whether the difficult part of implementing the feature is part of the enabling software or the hardware).
