Despite Jackson being in the final, I feel the most important thing of value to him would have been an eviction earlier in the show.
If he learned that this kind of perpetually altering demenour is not an asset in life, he would have gained a kick start in the path of wisdom. He's young so plenty of time ahead, but he could have won from a 'lose'.
There's still in upside of his participation, since he will recently feedback regardless when he leaves the house and he can see for himself and adjust if he sees fit and is so willing.
The nakedness is perhaps something he will see as being an obvious ditch effort like most did.
The strongest asset of a human being is surrending to their true self. It's is the great 'leap of faith' and the true 'naked' way of being which delivers a grail of dividends.
