There is no problem for several of us in going (not on logical consequence,
but on reasonable assumptions) from
(1) 'This thought' -> 'apparent physics-governed world' -> 'all logically
possible universes'.

The problems can occur when instead people do things like
(2) 'This thought' -> 'all possible thoughts'
(3) 'This thought' -> 'this monad' -> 'all possible monads',

where, if (2) and (3) do not bring in something akin to physics at some
stage, they will fall foul of what is effectively the white rabbit problem
(aka induction failure problem), unless some other factor can be invoked
which effectively gives priority to simpler universes / ordered thoughts.
