That's QM+collapse, but the collapse is not well defined,

It is well defined in epistemic interpretations.  But those rely on an implicit 
dualism.

and many incompatible theories are proposed for it, and Everett showed we don't 
need it,

But then we need to derive the classical world from the quantum.

if we assume comp or weaker.
Feynman called the collapse, a collective hallucination, but then with comp so 
is the wave.

It is misleading to use a non understood controversal idea in a domain (the wave collapse in physics) to apply it on complex non solved problem in another domain (the mind body problem).

There are no known phenomena capable of collapsing the wave,

Decoherence theory provides a mechanism, although the basis problem is open. It is of a piece with the problem of deriving the classical from the quantum.

nor any known evidences that the wave does collapse.

Collapse appears all the time, and a good theory must save appearances.
