First MC's story was already told, he triumphed, he got his harem and happy ending. Any more of the story and it would have just been like the tv-series Prison Break, which had great first season and iirc was originally meant for single season series, but got so popular that they just basically recreated the first season few more times. Later seasons were just pointless tack ons that lessened the value of first seasons. That's why it's good idea to end stories when there's natural ending point instead of artificially continuing them. Also even in incest game there can be limits in who the MC fucks in their family, if the idea is from the start that MC is going to fuck his future daughters, then that sounds lot like MC would be grooming them from the start to be his. And i don't know about you, but i find grooming to be mood killer in pretty much vanilla feel good incest harem story. Not to mention that with the side LIs added, he already has as big of a harem he could have time to take care of.
So you're saying that only way to be good parent is to monitor your 18-year old kid 24/7 and control their life to the point where they don't have any agency in their life to be a good parent. Man, that's seriously fucked up view of good parenting and i seriously hope you're never going to be a parent, without seriously growing up and learning that the kids need to learn to be independent and make their own decisions, instead of parents constantly monitoring them and making all of their decisions for them. Good parent is there to provide them with love, acceptance, and care, while also teaching them about life and letting them become the independent person they should be. Good parent is there for their kids when they need them and not be overbearing and over controlling tyrant.
