Which is exactly the position with over 18 sibling incest.
It's better that it doesn't happen, as it is of course foolish 'for all kinds of reasons'. Replace 'foolish' with 'objectionable' or 'wrong' and that is the reaction to sibling incest.

You seem to have got there in the end.

No, because replacing "foolish" with "objectionable" or "wrong" is begging the question.
There's no justification for replacing the predicate "foolish" with the predicate "wrong" - they don't mean even similar things. Smoking is foolish; riding a motorbike without a helmet is foolish; attempting to clean your upstairs windows without ensuring your ladders are secure is foolish. None of them is objectionable or wrong.

Lots of people do lots of foolish things all the time. That's not a moral objection.

Riding a bike without a helmet is objectionable due to the knock on effects on other peopple should teh rider crash.
It's irresponsible.

I think you might be nitpicking a bit here

Right. So, when there's third-party harm, that does alter things.
But merely being foolish isn't harmful, and - besides - it's not clear what third-party harm there has been when A shags B. Even if there were some harm, you'd still need a separate argument to show that it's sufficiently great to warrant curbing A and B's liberty.

The point stands that "foolish" per se does not imply "wrong".

I'm in very late here, but
the third party harm is that self-loathing over the whole thing is a good chunk of what's turned Bert into such a deranged wankstain and lead to his treating some of my friends in a frankly appalling manner.
