Honestly, I'm more inclined to just mail someone some cash in exchange for their services printing/binding/mailing the book back. Seems a little more straightforward than transferring bitcoin and having a noisy drone drop a book on my lawn. Plus, why would I want all my transactions on a public ledger? ;)

I don't have any bitcoin, but I would pay extra to have a drone wake up my neighbor's dog every time I buy a book.

Of course, whenever I say bitcoin, think monero. And if you know their address, so do the feds ;)
