Calabria's position is clear, and he is the author of the book. But last I checked, he speaks from FHFA position not any official Treasury position. You repeating "Treasury thinks it's illegal" is a highly inaccurate and liberal use of a book quote. There may be a PERSON or PEOPLE at Treasury who thought that and may have stated such to Calabria. However, someone thinking it does NOT make it true that it is in fact illegal. You keep acting as if it is because it's in a book.
I know you can follow this train of thought, you simply refuse to.
