The first goalpost was guardians were, in your own words, "private from each other" and "can't collude". They absolutely can collude, and "private from each other" doesnt mean they didn't preliminarily know who each other was in the formation of a federation. It also doesnt mean means they can't discover each other's npubs, which dovetail directly into multiple private messaging protocols over which they CAN coordonate and collude in a manner opaque to the users. If the goalpost is now "cannot geolocate each other", I never claimed they could.
