 Rigidly requiring fixation reduces the reach of copyright by restricting the number and kinds of work to which copyright can offer protection.This favours the public interest in the sharing and dissemination of information at the expense of the creator or author receiving a just reward.In the US, this tipping of the scales in favour of the public interest sits well with the general approach to copyright protection, the aim of which is constitutionally mandated as the "Progress of Science and Arts".
