Another theory why interspecies breeding/sex is prohibited in the world of Monster Musume could be due to Japan's long trenched history of xenophobia towards outsiders as well as Japan's declining birth rate. I guess that the right-wing factions in the Japanese Diet didn't want their country's population being replaced with demihumans/liminals when they're trying to get the number of human births up.

Also, Netherith. If you read the manga and watched the anime, the laws regarding interspecies breeding/sex is still in place and were so when Kimihito was forced by Smith to become a guinea pig for the Interspecies Marriage test case. In short, if he had sex with the girls in the house during this test case, he would still be sent to jail and girls would be deported back to their homelands (and that includes the girls successfully raping him).
