My point is that linearity appears to be essential, and that it
deserves an explanation. I give what might charitably be called a
speculation that it is related to "causality" of the multiverse (or
subset of the ensemble (aka plenitude, although I avoid that term in
the paper). Of course, if anyone else has a better idea, I'd love to
hear it!

Not equivalent per se, but exclusion of the white rabbit appears to be
necessary in order to justify the laws of physics.

Incidently, when do I get an eprint of your white rabbit paper?
