Perhaps a more interesting question then is why does this tedious nostalgia persist? If our new tools are not providing for our needs then we should change them to do so.
On the other hand, one big "need" is simply for the familiar, and another is to be different from the crowd. Old timers will hold onto their vinyl because it brings back memories that cannot be replaced, while young hipsters will buy them because no one else their age is. Simply being modern prevents new audio technology from fulfilling either need.
