How can one lose at minecraft?

Minecraft is not like most other games, there is not one objective that you are supposed to achieve, you can mostly do what you like. One could say that by killing the ender dragon you are winning the game and failing in an attempt to do so is losing, but the thing is that you can always just go back and try again, what you built will still be there, you can get your things back, in  the end one can not really lose at Minecraft forever because you can always just regain what you lost, unlike in other games where if you die you lose and have to start a whole new game. The only way one could really lose a game is if they entirely destroyed a necessary resource, which wouldn't even be losing because the only way one could do that is if it's their goal in the first place.
