*I didn't assume anything, except that plane waves will never be observed (regardless of your model of external reality) unless you agree to instantaneous action at a distance, and on steroids (!), since as time evolves, the amplitude of a plane wave changes instantaneously in all infinite directions. So I am just asserting that Tegmark's MUH has been falsified since plane waves mathematically exist, but are never reified by whatever is out there -- matter, or nothing but restrictions on motion giving rise the illusion of matter or something solid existing. Incidentally, I don't think the Wiki article refutes Tegmark as you claim; rather it just describes it.
