Just, that is why I wrote "it's just potentially harder for the EU to enforce meaningful penalties for infractions." You premise is true in one sense, however, the point remains - the GDPR covers all EU citizens, regardless of where the company is based. For small US companies, sure the EU has very little power to enforce it, but larger companies that derive any revenue from the EU can be, and are, fined by the EU GD…
I get it, but the operative point is not "potentially harder", but "literally impossible" to enforce -- unless the corp has some presence in the EU of course. FWIW, I just checked Wikipedia to sanity-check my memory of our lawyers' guidance. Important differences from our discussion, if my read is correct: GDPR does not apply to "EU citizens anywhere in the world", it applies to the personal data of "living persons .…
Yes, technically if the EU citizen remains outside the EU for the entire lifecycle of the data up to and including deletion, then it isn't covered. But if you store that data at all when they have returned to the EU, then you need to comply with the GDPR in terms of handling that data.
Also, as a UK citizen (formally EU citizen), I don't understand why US-based countries are so against the GDPR, as essentially it's just a codification of how to do the morally best thing for your customers. Any data you don't need for a business purpose should be deleted as soon as possible. You can have any data about someone as long as there is a justifiable business reason for it. You have to let someone know what data you have about them (if they request it via a SAR) and you have to give them the information up front to determine if they are happy with you handling their data, via a clear privacy policy and opt-in to having their data used.
Complying with the GDPR is pretty straight forward, as long as your intention isn't to profit by selling or otherwise making use of people's data in ways that they wouldn't be comfortable with. If you aren't doing anything bad with user's data and already following good security practices, including deleting data that's no longer needed, then you are already compliant with the intent of the GDPR and going from that to full compliance is probably only adding processes to be able to handle an SAR.
