Martijn van Dam, a member of one of the bigger political parties in The Netherlands said, “Taxing Internet traffic is great way to compensate the Music Industry for the loss in sales by illegal filesharing”. He added that a prerequisite would be that DRM and copy protection should be abandoned. The battle against piracy is lost according to Van Dam, he says that the Music Industry has to accept that their products will be traded over the internet.
The article notes that, in the past, Holland had discussed the possibility of taxing MP3 players themselves to create a similar solution, but that the proposal was eventually dropped.
But would the general public support a law that taxed them for use of something they've managed to get for free just to promote compliance? I'm not sure how government works over in Holland, but this idea seems dead in the water to me.
