Wherever did you acquire such a strange idea?

From my orthodox Jewish roommate, whose Tanakh had no vowels.

Yes, it has no vowels. But not for the reason you suggest. Your assertion that the purpose was to "make it impossible for anyone to read the Bible without a rabbi" is as false as the Protestant claim that the Catholic church only allowed Latin bibles to "make it impossible for anyone to read the Bible without a priest".
