A large part of the issue of this argument, and really the fundamental, decisive counterargument against all ideas like this is that coordination isn’t required to expand.
A good analogy is how chimp-like creatures 4.4 million years ago kept expanding and contracting, as well as speciating, but where the forces of expansion outweighed the forces of contraction a little bit, and this eventually produced our own civilization without any global coherence necessary.
More generally, you substantially underestimate the power of “it only takes one group to expand” to defeat most proposed Fermi Paradox solutions, and this is a major part of what made solving the puzzle hard.
@Zsolt Kelly-Bene, I would recommend avoiding Fermi Paradox solutions where it isn’t remotely plausible that all such civilizations choose not to expand in the universe, because they are very unlikely as a conjunction of claims.
