I really liked her and personally find her my my type, but she was outclassed by Cappy as a dating choice for Rodney. Rodney had a choice between a boisterously immature outmode with a school girl crush on him or a literal super model female executive with empathy who over time came to like and help Rodney out of respect for his cause and not out of a crush like Cappy.

>Piper not being the love interest fucks the entire story's moral up.
It doesn't. It is the classic "princess falling for the pauper" archetype where despite someones luxury and higher standing they are able to recognize and appreciate someone who by their society would treat as a lesser. Rodney being able to break that class boundry with his vision and ideals is a pivotable moment and marks his rise from underground personality to an actual figure of change. He never had any interest in Piper and didn't "forget" about her. By that point of the movie he was trying to find Bigweld, something Piper herself encouraged him to do early on in the film.
