Members of Congress are vetted by those who vote for them. Many do choose to reveal their tax returns and, of course, all presidents since Nixon have done so. A national vetting if you will.
Actual fairness demands that you be as outraged as you would be if either Obama or Clinton withheld their tax returns.
You would lose your 'wager', bigly. And I'm pretty certain that you know that.
What we're looking for is kompromat that may influence foreign policy decisions, that may motivate a president to speak glowingly of 'strong and powerful' denials from a Russian thug.
The law says 'shall turn over....'. Purpose and motive are nowhere mentioned in the law that the Treasury secretary is violating.
Pretty ironic for you to speak of empty brain cavities when so very many of your posts reveal so much word salad misinformation and so many conspiracy theories taking up residence in your own VERY spacious digs.
