Right, but since we have no scientific basis for figuring out which capabilities those would be, the reasonable guess is that EM is the best means of communication. It's more likely that we've figured out some basic physical limitations, even if there exists technologies within those limitations far beyond what we've though up so far.

Sure, and as I mentioned in my comment, I agree there isn't much value to speculating what these unknown phenomena or technology are. But, the value to recognizing that there is non-zero probability that they exist prevents us from making overly confident statements such as "the reason we haven't seen radio signals from other civilizations is because we are the only intelligent species in the universe"
