To support just ONE country requires one set of lawyers. Supporting the second country DOUBLES the number of lawyers required, while adding only a fraction the number of customers. Once you scale it up "most of the world" the economies of scale kick in and the lawyers aren't so expensive anymore. Of course, "lawyers" here is shorthand for several things. Complying with local law, handling local language, dealing with local customs, etc. "Lawyers" is a convenient shorthand because it points out that some of the things actually MUST be dealt with. Google doesn't prohibit the use of their payment system because they dislike having customers outside the current limited list of countries, they do so because they aren't smart enough to figure out how to handle every country!
