The OP describes a scene of incest, then asks "Was it OK?" given that there was no "harm" done to anyone, and suggests that we should approach this rationally.
But we shouldn't approach it rationally.
Yes, we should.
Disgust isn't rational.
I agree.
Neither is morality, at its core.
I'm not sure where you going with that, but I consider morality to be an ingrained piece of our humanity. Details of which can be left to the individual, but there is a certain consensus of right and wrong.
The OP scenario, in my opinion, did not cross any boundary into wrongness.
A bit icky, perhaps, but not really wrong.
We aren't disgusted by incest because of some balance of utility weighed in our heads.
So it's ridiculous to propose that incest is not disgusting when no one is "harmed" by it.
I would use the term 'availability' rather than 'utility'.
There are many types of incest that I would consider to be heinous, but the fictitious example given is not one of them.
