I built a house recently (admittedly not millions) and paid some of the subcontractors in cash. Where do I go to turn myself in? Or will a government re-education center be sufficient?

Exactly

Check any bill in your pocket it says "THIS NOTE IS LEGAL TENDER FOR ALL DEBTS PUBLIC AND PRIVATE" That is right on the US currency

Who the hell has the right to tell you you have to use a banks service in the form of checks or credit cards
That is tatamount to forcing you to use any private business

There is no requirement to use a bank; it is legal to use cash; but under some circumstances, the law requires that the person who receives the cash report that fact to the Government. As I pointed out above, those laws were enacted by Congress at the urgings of Presidents Nixon, Reagan and Bush (Sr.), on the rationale that if we investigate anybody dealing in large amounts of cash, we'll be able to catch the drug dealers better.
