Broadly agree BUT there are still advantages to copyrights on works that are still commercially viable. Seinfeld was made on film. Without copyright, someone would have to be incentivized to acquire the original reels and pay to digitally scan all 180 episodes of film, knowing that the resulting scans would also be in the public domain and thus very difficult to recoup their investment on. So in an alternative reality where Seinfeld's copyright expired, its possible that SD TV captures of all the episodes would be free and publicly available (great!), but an HD conversion would never be made (not great).
