I saw it, but I was confining discussion to Manasson's theory explicitly, possible modifications are hard to discuss if they are not developed.??? Did you miss that I specifically said that the entire scheme can consistently be made non-local using spin network theory or (the mathematics of) twistor theory?
Manasson's theory only explains quantisation; it isn't a theory of everything. Just adding spin networks to Manasson's preliminary model alone already seems to solve all the problems regarding being able to reproduce QM entirely.
However to discuss that, I get that it might seem that spin network theory will solve the problem, but I would suggest reading up on current work in Quantum Foundations. All realist models (any of nonlocal, Many-Worlds, Retrocausal and Superdeterminism models) all display fine tuning problems as shown in the Wood-Spekkens and the Pusey-Leifer theorems for example. It's not enough that something seems to solve the problem. If you try an unnatural fine tuning will emerge.
