I think that's a misapplication of Occam's Razor. I'm not sure how exactly you're using contrived here, but the idea that complicated interactions like the ones we experience are likely to exist inside simpler systems is seeking the less contrived reason for existence. I'm saying that it's likely in the same way that virtual machines are likely to exist inside networks. Virtual machines might be more complicated than operating systems running on bare metal, but it's simpler and easier to create a thousand virtualized environments than one additional bare metal computer by orders of magnitude. In the same way, if it's possible to create nested experiencable universes, the total number of virtualized environments experienced is likely to be much greater than the number environments operating on the most bare, fundamental principles of existence alone.

This simulator's world is less likely, because it consumes more resources: needs to run thousand nested worlds, so their probabilities are reduced proportionally and further reduced by the virtual machine itself. Also bare metal is more efficient if virtual machine properly interprets instructions and doesn't merely forward them to processor.

Consuming more resources is a matter of perspective, not efficiency, because the scale of total phenomena would be much larger than what is experienced. Always bet against the comprehensiveness of your comprehension.
