The issue I was talking about here was whether my insistence on following all of the necessary steps for verification in the scenario that we had been discussing was because I believed that such seeming pedanticism was a method to prevent collusion.  I just pointed out that no amount of verification of the key can prevent the key owner from sharing the key or messages encrypted to it with other people.  There is no need to believe that verification does not yield certainty in the ownership of the key.
