I was more thinking along the lines of making a web app instead of a native app; IMO Google's implication is that, if you're not doing business in one of the supported countries, you're not allowed to conduct commercial transactions through your app. I'm guessing that this is more a legal issue than anything else (not to mention the developer getting around the kickback Google should be getting); I can imagine it sucking for Google to have accounts frozen because some auditor found out that Google was indirectly doing business in an unauthorized country. There could be tax issues, compliance issues, issues with trade agreements -- there are a TON of things to think about.
