Who is to say we wouldn't also include two or more other great composers in that list if there hadn't been a 21 year statute. Sometimes a set of factors just seem to line up perfectly to generate amazing ideas in the right people - it's why people independently come to the same conclusion or invent the same invention at the same moment in time. Copyright law minimises the benefits of these "golden ages". With longer periods of copyright law (in excess of lifetimes/generations) copyright law can simply destroy the potential value of society.
