I don't understand why that is necessarily a bad thing. If someone is looking to make a shit ton of money, have a chance to monopolize or dominate the international market, then yes, that makes sense. But if you're happy and content serving nationally, and so are your customers, I really don't see why someone would want to expand internationally.
