It is plausible that regularities are a required feature of

This seems very likely, but it does assume something like a string
landscape in which some regions don't contain regularities. Or to put
it another way, regions in which maths doesn't work. This seems to be
out-Tegmarking Tegmark, who assumes that at least maths is (meta-)
universal.
At this stage, it's no worse than assuming meaning generation is a
necessary feature of existence, and that this can only take place by
compression of regularities, which is the Solomonoff type answer...
That would require a source of such regularities, surely? But that
would seem to lead straight back to requiring that maths works.
However, neither does Bruno's theory does not offer any explanation
for the 'uniformity of nature'. He has to appeal to religion to magic
away the 'white rabbits'. According to Bruno's account, the physical
world is not even Turing emulable -- which one would think would be a
requirement for regularities that could be described by physical laws.
(If the physical laws are not computable, in what sense could one
describe them as laws?)
The randomness of QM is not computable. Bruno's idea is like MIW,
indefinitely many worlds are computed/emulated in parallel and in the
Born rule proportion.
The Schroedinger equation is perfectly computable. The many worlds of
MWI are computable -- we have 1p inderminacy, but we have been assured
that that is all part of the dovetailer -- totally computable.
