Functions are abstract mathematical entities, so the quantum wave function cannot be the basis of physical reality, which must itself be a concrete physical entity (a quantum field?). It can at most represent that basis mathematically.
According to MWI, the wave function is reality. In what way is a quantum field a "concrete physical entity"?
