CMV: the ending of Wall-e was tragic [spoilers]

The ship computer, Otto, did everything in its power to keep the humans on the ship where they would be happy. Despite this, the captain followed his naive curiosity into certain death. The humans have degenerated musculoskeletal systems and will not be able to perform the manual labour necessary to rebuild an earthbound society from scratch. Not to mention the scarcity of natural resources and the regular sandstorm that could kill everyone if not destroy any progress building infrastructure that they may make. The robots would be of very limited utility as they are all specialized to work on the ship, not build homes, water recycling facilities, and literally everything else that makes up modern society. This will take a tremendous amount of labour, a sharp contrast to the humans hedonistic life on the ship. 

The only hope the humans have would be to give up on Earth and make it back to the ship before the next sandstorm, but that seems unlikely. 

CMV!

I don't feel like semantics are useful here, especially from a childrens movie.

I think the intentions of the story and the underlying message are what's important. Wall-e is about human curiosity and the way humans can become stagnant, or delude themselves.

Wall-e was basically just posing the question, is it better to live a lie, or a less whimsical truth?

But at the end of the day, you can have both, the ship is an endless supply of food and water, it would be very easy to simply be moderately dependant on it until infrastructure could be reinstated. They don't have to go back to the ship entirely to use it's resources. Also considering the great feats capable by the machines on the ship, human mastery of the machines once more is an inevitability.

So no, even in a realistic world the humans in wall-e would not have died.
