I don't know what you mean. What "fact/value distinction"? There aren't any value-free facts for a naturalist (of my persuasion). — 180 Proof
This is what I mean -- dithering the distinction between fact and value means there aren't value-free facts. Where Hume states the logic between the copula and "ought" creates a non sequiter, the ethical naturalist will say it creates a condition of satisfaction, or something like that -- a natural, ethical fact.
For instance, suffering (e.g. harm, deprivation, bereavement, etc) is a functionally disvalued fact, no?
Yes, I agree.
As for Hillel's maxim: "what you find hateful" – whatever is harmful to your kind – "do not do to anyone" – your kind. It's not a "command", it's a normative observation. — 180 Proof
I just mean the form of the sentence -- it's in the form of an imperative, rather than in the form of a statement.
"If you and yours functionally avoid harm, then you ought to avoid harm"
So the first part of this conditional is a statement, and the second part is also a statement that switches out "is" for "ought" - what Hume calls into question. One response to Hume is to point out that this is exactly how one would "derive" an ought from an is within our logic, and point out that a conditional is in the form of a statement -- that is, it's functionally truth-apt, regardless of how we might feel about "ought" being spooky.
And, as you note, there is certainly
regularity in nature -- a regularity that, as long as we're not obsessed with universality, is still pretty dang regular: human beings, on the whole, seem to want remarkably similar things when we consider the formal possibility within existential ethics, whereby master can smash the old table of values and posit new ones in their place.

It sounds funny to our ears which have been trained on Christian ethics, but I'd say one thing in favor of Epicurus' ethics is that it's actually
hard to be happy. It takes effort. We have an irrational aspect to ourselves which allows us to attack our natural desires, or create desires which run away with themselves.
As scientists these divergences are as important as the convergences: there's nothing ethical or good about any one path except insofar that a path helps that person become happier.
But if that's the case, then we're back at the problem Hume pointed out: just because there are many humans who are happy by being married, with children -- not all humans want to be married, with children. It may be the case that Man, as posited by modernity, is the master of his destiny, but should he be?
Basically Moore's open question argument still punches, for me, in spite of all the attempts at making a natural ethics.
