You still have to go online the first time you install the game to check if the game has not been locked to an account. That still defeats the purpose of pure off-line play.
Your hurdle can be solved by letting the second install undo the first one. Say you've conveniently forgotten you had registered your game to your account. When who ever you sold the disc to starts the game up for the first time, it will be removed from your account. (of course then you can sell it back to a store and still enjoy the game until it has been resold)
Either way, online check when installing is still required.
