I don’t really follow this. Things in Platonia or Tegmark level IV don’t have separate probabilities Any coherent mathematical stucture is guranteed to exist. (And infinite ones are no problem). So the probabilty of a infinite stack of metagods depends on the coherence of a stack of metagods being considered a coherent mathematical structure, and the likelihood of our living in a Tegmark IV.
