>and whenever it's brought to the surface, it evaporatesIce doesn’t suddenly evaporate on contact with the Martian atmosphere.
> Not even the sun is infinitePractically, it is. You’re being pedantic. By the time we “run out of sun”, it will have incinerated Earth billions of years ago, so we’ll have vacated the place, died out, or switched to an alternate energy source by then.
> We never considered the possibility of depleting it's resources globally. And it’s still not a practical concern to deplete Earth’s resources. Counting only known reserves of exploitable crude oil, oil sands, heavy oil, and very heavy oil, we won’t run out of oil until the 2200’s.
> So we will end up inevitably in a desert island situationNot possible since solar system resources are practically infinite. You could try dismantling Mercury and use it’s material to construct a fleet of thousands of super star destroyers, and only reduce it’s mass by a few percentage points. You could outgun the fictional Galactic Empire without leaving the inner solar system; that’s how plentiful resources are on that scale.
