Try disobeying a judge and see what happens to you... it won’t go any different for you.
It’s not because of a law written by any court, it’s because of a law passed by Congress, specifically 18 U.S.C. §401 (1964), the federal contempt statute.
As far as 9th/10th Amendment jurisdiction is concerned, I wholly agree. But if those Amendments are suddenly in force again, 90% of the federal government has to be unwound - and the sad truth is that 90% of this country doesn’t want that to happen.
It would have taken less space to just concede your false assertion.
