1) "GDPR is europe's problem" --> I'm saying it's an attempted solution, not a problem
2) "not of the entire 'email industry'" --> the whole 'email industry' is in fact, affected. Where you operate from isn't a factor. Only if you don't email EU citizens (which is quite unlikely), you don't have to worry about it. If you do (which is very likely), you should know and implement GDPR rules.
I understand your FACTA analogy, but don't see how you disagree with me.
