Based and incestpilled.
Phrasing regurgitation aside, these truly are the relationship dynamics that have the greatest potential for success, with very clear dynamics that form naturally, and without need of explanation to either party involved.
The Mother+Son dynamic is a bit more questionable, as most women tend not to naturally feel legitimate love for any of their children in the first place, ESPECIALLY not their sons, but it's also relatively easy for a son to slip into the role of a husband for a mother, and become a target of her long-lasting affections, provided the mother isn't repulsed by the idea. Anything short of revulsion though just leads to it being another thrill to them. Women will take their thrills wherever they can get them. The other concern with Mother+Son situations is that, by necessity, the mother can't be the sole parent. Simply put, the son still MUST have a father. Mothers are, in the vast majority of cases, simply incapable of being even half way decent parents, especially without a man's direct guidance.
Another dynamic with serious potential is the classic older brother and younger sister combination, but it's more dependent on individual personalities and dynamics. I'm fairly sure that it's pretty heavily reliant on the older brother maturing early and quickly (which generally necessitates being the oldest of the siblings, if there are more than two), and the younger sister having both a naturally submissive personality, and the father playing less of a significant role in her life, essentially creating a pseudo father+daughter dynamic.
And agreed on reproductive incest. The only way to justify it is by outright supporting eugenics, especially since the potential complications of genetically close inbreeding are negligible (relative to non-inbred offspring, of course) for the first few generations in most cases. You only really have to start worrying about things once problems actually begin to arise, and even then, it would be the choice of the couple whether or not to take the risk. To separate the two in favor of manipulating the genetics of the offspring to be "superior", is to enforce eugenics.
I haven't heard the proposition to integrate adoption to help sidestep the compounding genetic concerns before, truth be told (though it seems painfully obvious now, seeing it here), and frankly, it's a pretty elegant solution. It nips the number of orphans in the bud, while also promoting the continued structure of these healthy parent-child relationships. I could also see arranged adoption, of sorts, akin to arranged marriage, where families agree to raise each other's children from birth in order to encourage genetic diversity, while maintaining these relationship dynamics.
As you said, incest should be legalized, and adoptions made easy.
