Assuming this is correct -- I don't know enough about the publishing biz to say for sure -- what you are describing would amount to a mere breach of contract claim between the publisher and bookseller. It would not be "illegal" in the sense that that there is a law on the books somewhere that prevents the sale of coverless used books.
You, in your capacity as an individual, could, for example, sell a coverless used book at a garage sale with no penalty.
Unless there's a law out there that I'm unaware of (in which case I welcome correction), I call shenanigans on the "coverless book sales are illegal" claim.
