It still exhibits evidence on the part of the infringement prosecutor's clients that they haven't quite grokked the Internet.
It's like a famous person requiring the removal or payment for all photos of them throughout the web. All they'll end up doing is removing themselves into obscurity leaving the field open for those unconcerned by the revenue 'lost' through fame.
If you create a device that adds friction to information, you don't generate revenue, you devalue the information, and lose revenue from market alienation and decreased promotion.
A lawyer with a far better grasp of friction and copyright is Lawrence Lessig who long ago realised that if you create a device to remove friction from information you increase its value, and gain revenue from increased promotion. This mechanism is the assortment of Creative Commons licenses. This perversely confuses people into thinking that it is copyright that enables the granting of liberty, but that's another matter. The point is, that each member of the audience is more valuable than each copy, and the audience values the artist far more than they value the publisher.
The only benefit an infringement detection device will have to society is in hastening the demise of those who believe the public does not deserve liberty to enjoy, share, and build upon public works.
