Avi K – I have to agree with others that you have a tendency to nitpick which is unhealthy. An analogy is not supposed to be analyzed with a fine tooth. Rather it is a comparison of the main point. My main point was that it is well known that the Gedolim of each generation seek out those that will be the next Dor’s Gedolim and reveal them at the right time. If you come from a DL background it could be that this concept was never told to you.
In regards to Daat Torah, in light of the topic at hand (Zionism-Apikorsos?) and in light of your definition of “Daat Torah (…means that gedolim have either a mystical power… to decide questions which are not halachic.) I fail to see what “Daat Torah” has to do with what the Status of Zionism is. Both HaRav Kook, z”l and those Gedolim that opposed him in regards to Zionism held their opinions purely from a Halachic perspective, each bringing Torah sources to back their discussions. This is no different than any other halachic argument. Even those topics such as “serving in the army”, “working vs. Kollel”, “voting”, “taking money from the Medina”, etc. the Poskim (including Rav Druckman and other leading DL poskim) are all arguing their side purely from a Halachic perspective, not from Political or personal preference. All the more so, from a “mystical” power. Daat Torah plays no role here (based on your definition).
As far as the topic at hand, the poskim argue. I assume that those Gedolim that oppose Zionism and call it Apikorsos are basing it on their understand of the driving force behind Modern Zionism and what are the Gedarim that constitute Apikorsos.
