Not read the whole thread, but I found this insightful
The basis of the happiness result, either more or less happy, is the consequence of choice/action
If we lack moral responsibility, due to determinism, then presumably we are not morally responsible for the happiness we create for ourselves, nor free to squander/enjoy it. That would defintely take the sheen, if not the shit, off of things for many.
If it just comes down to
ought implies can, then desserts (rewards, fruits of labour, whatever) would analogously imply they can be withheld by others and/or fail to make us happy. Not saying that happiness must be moral but that happiness involves
chance or choice, not just action.

something which, compared to mankind in the mass, appears as a sort of superman. Such happy strokes of high success have always been possible, and will remain possible, perhaps, for all time to come. Even whole races, tribes and nations may occasionally represent such lucky accidents
(antichrist 4); it's a phrase that reppears similarly in the gay science 995
owing to happy and reasonable marriages and also to lucky accidents, the acquired and accumulated forces of many generations, instead of being squandered and subdivided, have been assembled together by means of steadfast struggling and willing. And thus, in the end, a man appears... and the wretched intellectual play of aims and intentions and motivations lies only in the foreground
There may be be some
contingency to greatness (or happiness), though IDK enough about it to have an opinion...
