We intend this to be a measure of deregulation. The word "passport" can be misleading. There is no passport officer and no physical passport; the term refers to a mark that can be applied by the propagator himself. We intend the regime to be as light as possible, but we also want it to be applied as sensibly as possible and—this is most important—as universally as possible, so that we can ensure that we are on a level playing field.
