If you look at the last few singles matches he's played, two of them have been losses to Zverev. Of course he doesn't see Zverev as any competition to himself, yet Zverev is succeeding and getting all the attention. This would be a quiet drip doing all the damage in Nick's head since around this time last year when Zverev won Rome. Two more losses and more Zverev success - definitely damaging IMHO.
And as for that match Vs Dimitrov at the AO, he should definitely have beaten Dimitrov after the way he destroyed Dimitrov in the Brisbane final. That tournament had me and quite a few others thinking he could win the AO. Seems crazy now but he was playing spectacular tennis.
Kyrgios is too lacking in real life experience to see how monumentally stupid he is in his career-related decision making. His family have cloistered him. He's not that different to Tomic in that respect. He'll only take advice from people he "respects", and I doubt Blake is one of those, however good it might be for him to get some perspective from people like Blake, Hewitt etc who climbed the mountain multiple times.
The really crazy thing is he has all the weaponry to succeed on clay too, but it's just too much hard work.
I'm sure all you're saying has some element in this all, and I am sure he is more than deficient in many ways character wise, but I honestly believe his issue is what I, and Alba Barragan above, are saying. It is some issue in his head to do with losing, the "I don't care enough to even really be here" is his plausible excuse card in case he loses.
He really needs a mental circuit breaker, some way to relieve all the pressure and expectation off himself. Or some way to escape this identity he has made for himself which has turned into like a prison. Maybe just go as dark as possible and just slowly chug around the lower tournaments to get the feeling of how to win again, get some confidence, but with his head down, then just be that guy you didn't notice get through to R4 of the USO because he did it so quietly and boringly. giving the media nothing, they'll move onto zverev or djokovic or someone else. I dunno, just throwing ideas out there. Maybe get Magnus "the head doctor" Norman on his team?
McEnroe as his coach was a horrible idea, it would have been a nuclear circus on meth.
But nothing will happen, he'll just repeat the same patterns then go down the drain, and will be just another "could have been" that will be eventually forgotten.
edit:
I dunno, maybe even start playing for Malaysia(?) where his mother comes from to escape the Australian Media, who are like feral terminator hyenas that never stop.
