I have read through some of your thoughts and opinions. I don't think you will be convinced or persuaded to see things any different then you already do.
I do think that tarot is random, I don't think that there is any subconcious shuffling going on. I think that there are enough meanings and translations for each of the cards for a person to "associate" a meaning that fits. That I think is drawn from the subconcious if it is not "spelled out" so to speak.
I think a lot of Tarot, is mostly association, creative intuition, comparison, and memory.
Not really much different then studying a book, that you may have a test on later...
Is tarot Magic? It could be for some. I personally say yes. Only because I don't think (even though it is fun to try) that it can be completely explained or disected. Magic could be defined as "Characteristic of something that works although no one really understands why".
It is in an interesting topic, although I don't really think that there is a solid answer. Tarot works, and it is pretty darn cool.
The only qualm I really have is with the questions that some folks may ask. Then I don't see Tarot being used effectivly for what it is, but then you would not use a hammer to clean a window either? They are tools for deep thought, meditation, and magic.
