Not to mention this doesn't even solve the problem. What's preventing someone from registering and then releasing an app with a similar name to a famous app? Sure, the registration means there's someone you can sue, but it doesn't allow the user to identify the publisher. A "verified publisher" field when you're installing an app would solve both issues (similar to windows[1]), and not require every app developer to register with google.
