Verhoeven completely misunderstood the book, was the thing, and made a parody of it. What he missed, what Heinlein's reader's often miss, is that Heinlein doesn't write utopias. None of his books are some imagining of an ideal society. The point of Starship Troopers was to explore in depth what life would be like in a militaristic/fascist society from the point of view of someone who knew nothing else. It was subtle and powerful as a result: the point-of-view characters are fully adapted to their society, and don't point out all the ways it's batshit crazy. Heinlein trusts the reader to make that call, to see how easily people get used to even such a harsh society and accept it as normal, if that's all you know.
Verhoeven missed all of that, saw it as an endorsement of the society in the book, and parodied it, turning the really interesting point the book was making into trite anvilicious crap.
Moon is the same - exploring an ultra-libertarian society in the same detail, in the same way from the point of view of people adapted to it. I expect the same Hollywood treatment: making a satire of it since they see the society as unwanted, not realizing it wasn't an endorsement in the first place but a critique.
