That post mostly concerned infrastructure, you won't likely run the same managed DB with 2 different providers, for example, but you can well offer sign-in with EU/non-EU options, and as long as the first one is viable, I'd say that would already be a win in terms of OP's goals.

Did you try to register VAT-free by any chance? My first guess would be that you could have set the tax region wrong.

As in, that they won't run away when they see them or that they will all happily use them? If you mean the latter, then it's just false. Also, why do you assume that such product would need to be used worldwide all of a sudden? Having something for the local market would be sufficient to call it a success in this instance. There's an ICC judge who could tell you a thing or two about having a whole digital life on the hook of services from one country, so reducing this dependency is a clear benefit.

Sign-on with the external identity provider doesn't help if data related to your account like the billing information, your government ID info etc. are released in the breach, that's the sore point.

Sorry, I don't see your point. While lifting up the masses out of extreme poverty globally is obviously good, it doesn't transfer to your situation unless you happen to live in one of these upstart countries. The society you live in is not global, even if we share more of popculture and technology now.
