As long as a book pays, I'm not sure the Player has too much argument about the exact method (crypto, check, bank wire, cash in a bag). It is certainly less-important of an argument, compared to the primary problem of slow-paying and/or no-paying.
You're effectively asking the book to help you commit tax fraud. Which shouldn't be the book's concern at all. They're not responsible for the tax-codes of 200 different countries.
That being said, if the book does insist on bank wire for all withdrawals, it would be entirely reasonable for the Player to say "Going forward, I'll take my business elsewhere. Let me know if you ever change the withdrawal policy, thanks."
