Very interesting. You want the converse. The original statement effectively

"if the world is rational, then whenever an arbitray state is discovered, all
other possible alternative states must also exist." Hence the Plenitude.

The converse could be stated as follows:

"If all possible states are also found to exist whenever an arbitrary state
is discovered (i.e., there are no unexplained phenomena, no wabbits) then the
world is rational."

Experiments in Quantum Theory seem to indicate, in the small scale, that this
is the case.

I don't understand your statement about complexity.

True. I stand corrected. It does not prove the physical Plenitude. However,
it certainly expands the mathematical universe to infinity. Now if the
correspondance between the physical Plenitude and the Mathematical Universe
holds then my statement is still right.

We went through that many times. I draw the line as tightly around myself..
my mind as I can. "I think," this is my starting point. You don't have any.

The WAP filters what we can observe from the Plenitude. If you assume that WE
observations. Hence no arbitrary events. All is explainable. No Wabbits. This
may also be an answer to Jacques' post.
