You have to have everyone go into the splintered metaverses to avoid physical expansion. Everyone. Every biological body. Every AI. Every AI written for the specific purpose of having a long enough time horizon to settle new locations physically. Even the AIs written specifically to marshal together the physical resources to build more metaverse computing power. Even the AIs and fiesty biological bodies who one way or another end up with a 100% bias towards physical reality. Even the many, many beings who will quite accurately observe that no matter how short-term appealing this is a long-term loss. Even the beings who specifically want to be the ones in charge of the physical machinery and see an advantage to continuing to expand it. Every. Last. Being.
I don't think this degree of uniformity is plausible.
I reject this as an explanation for the Fermi paradox for similar reasons, except they're even more relevant across all of the putatively common alien civilizations. I don't even find it plausible that all of human civilization would do this, let alone all of every civilization ever.
