Think right now about your home bookshelf. If yours looks like mine, it contains odds and ends, comic books you’ve saved for years, books mailed to you or bought on a street corner, your own collection of dog-eared titles, some old yearbooks. Now think about the privacy of your own home and the few legal ways in which that privacy can be violated: an emergency response, a crime, a public health crisis. Imagine if once a year you had to open your door to a copyright agent who could scan your library for content that you have not paid for, add up your violations, and send you a bill. Imagine if the agent came by once a week, or even once a day. Imagine that the agent found a picture of the nerdy kid from high school in your yearbook and explained that that kid copyrighted his likeness, so you’ll have to either pay up or destroy his high school photo.
