No, I don't think that's it at all. The problem with Starship Troopers is not that it went to far in the violence or sex department, but that it tried to make satire out of a serious and interesting novel. Its a fun film, sure, but compared to the book its pale and watery and very unsatisfying.IIRC, Verhoeven was working on a sci-fi bughunt project that someone noticed was similar to Starship Troopers' theme and so elements of the book were merged with the original project.
Some of Verhoeven's work seems lost on most Americans, very satirical and pushing the envelope of good taste. He pushed horror-level violence , along with social satire, into action movies with Robo-Cop and Total Recall (which Americans, violence junkies ate up), and pushed sex with violence with Basic Instinct, another hit. But when he did a movie with lots of sex and nudity, Showgirls, it was met with hatred (though in the end it was actually anti-hedonism). When he made an action sci-fi that was propaganda satire and the heroes were fascist thugs...no one got it. He had pushed American audiences a bit past their limits, then went too far for them.
I appreciate Verhoven's style - the Robocop was entertaining, Total Recall was great... but I think Starship Troopers needed to be done by someone with a little more respect for the source material. It is, in fact, Verhoven who didn't "get it".
