Anyway, it boils down to enforceability. EU is a huge entity and probably will be able to enforce the GDPR by forcing payment systems and gatekeepers like Google and Apple that legally operate in the EU not to do business with businesses that do not respect GDPR. Maybe it will be a bargaining point in some trade talks between other countries and the EU and EU will insist that the countries will help with the enforcement of the GDPR in exchange for something that other countries want from the EU.
As long as we don't live in some kind of libertarian anarchy world order, these things will be determined by the politicians.
