There was an answer. You didn't seem to like it, but I think jdlessley's post gives the correct "by-the-book" answer. You're asking about a financial record, and there is a clear retention period for financial records.
If your priesthood leaders and auditors agree with your position that these records are unnecessary, then in accordance with that local decision you can feel free to destroy them sooner than the normal retention period.
Questions that can benefit the larger community should be asked in a public forum, not a private message.
