Because Fuji doesn't look like Kodachrome. If you like the look of Kodachrome, Fuji just won't do. As for Kodachrome being 'archaic and forgotten', I hate to break it to you. But this is true of film in general. If you DON'T want to shoot something that is archaic, consider buying a Canon 5DII or 7D.
