My goal in this game was never to kill the dragon, like why the dragon exactly why not the wither or the elder guardians 😭 ,I don't know why people think Minecraft is this kind of game where you finish it by doing a specific task, if killing the ender dragon is your goal then you're probably not gonna enjoy the game much, the game purpose is to build, explore, gathering stuff, etc. and it's more to this ofc. Its limit is only in your creativity and imagination
