Argument: Costs of unenforced copyright laws has grown
Barry Sookman. "The costs and benefits of graduated response in copyright enforcement." Barry Schookman Blog. February 1st, 2010: "in the phase of the digital roll-out, the benefits of the digitization could temporarily outweigh the costs of not enforcing copyright. But now that digitization is ubiquitous, there is less benefit and much higher cost with not enforcing copyright. Worse, if copyright is poorly enforced at the end user level — with free-riding going unpunished — then incentives are given to innovators to help the consumer to free-ride. The longer this signal lasts, the higher the cost of copyright enforcement."
