The gene doesn't have to be eliminated fully.
You could always get the gene suppressed permanently by a separate gene.
Though moids would stilĺ be involved in reproduction, and every woman would have to get one X chromosome from her mom's moid.
I imagine that it would likely be bred out if enough time passed while culling moids.
Then again i thought the whole raccoon moid thing came from moids being made the significantly weaker sex by sexual dimorphism, with women likely being made stronger as well.
I'm sure that if women were entirely in control over which men breed that they would weed out undesirable moids pretty early on.
And since women would be the same size if not bigger, we can assume that evolving smaller vaginas is off the table.
Therfore, raccoon moid dicks would be completely out of proportion with their body.
Taking this further, they would likely have more efficient hearts and lungs in order to not pass out from getting an erection.
