>A EU court can just order a whole-EU dns block for your site and any related urls and you would be incapable of serving any person from EU. They could do that, but it's certainly not within the scope of the GDPR - member states can issue fines and penalties, but if you have no assets in the EU that is the extent of enforcement i.e., none at all. The GDPR makes no mention about Chinese style firewalls or blocking European customers off from your business either, it is simply legislation for getting European businesses or foreign businesses operating within the EU to respect data protection laws. The more realistic alternative to foreign businesses not cooperating with the GDPR is that European businesses will voluntarily choose to not do business with you as they'll share liability for your non-compliance.
