> Is it fair for people from that 3rd world country to sell the book back to the USA and for you to miss out on your profit? Yes, and no better reasoning is required other than "It's my book now and I'll do whatever the fuck I want with it." If you restrict what people can do with their own stuff just because of the indirect effect on a current business model then you'll simply snuff out other (better) business models. Free and open-source software may have never become popular if MS had been able to complain that it was eating into their business model and affecting their ability to "give away" software to universities and schools, and that's just one example.
