still...
all your examples follow concepts which are grounded in our reality.
which have a base in our reality.
for even a concept as linear as a simulation...there must be an environment for it in which the apparatus operates.
There must be given natural laws there.
and to construct said simulation, the simulated environment must have some basis of the original built in.
One cannot build a cat without knowing of cats.
One cannot build an experiential universe without experiencing one.
regardless of the construction being done by a wet brain or a dry brain. Or both.
