Security is layered. A backup code is only useful with the password, and your password is only useful with a second factor. You can be fairly liberal with storing your backup codes: make a couple of copies, keep them in secure places (one at home, one in your office). I agree that backup codes aren’t perfect but they’re pretty robust.
