Whether or not this is a good or bad method, I think that the traditional Jew holds the Talmudic traditions more authorative than a private interpretation of the text of Tanach.
Am I correct in this?
The Talmud is not the only record of Jewish tradition. As a guide to practice, it would be quite confusing. It is a mostly a record of arguments and counter-arguments, using acronyms, allusions, abbreviations, and presupposing thorough familiarity with all of Scripture and other texts, and many times is not obvious about which views are correct or even acceptable.
Private interpretations are akin to homilies or sermons, perhaps interesting and instructive, but not determinate. From someone who is not a master of the sacred texts and traditions, private interpretations are almost always just childish delusions.
