If a business blocks EU citizens what will happens is that either another one who cares about GDPR will pop up and be able to work with both EU and non-EU citizens, or the business in question wont be that important in the first place. In either case, nothing will change for most people.

Maybe, but imagine if Google, Microsoft, Facebook, Amazon, etc. had decided to pull out of the EU. Not that any of them aren't replaceable, but providing the suite of functionality that any one of them does to their customers would not be a simple feat.

"Second class citizens" might not be the right term, but would "segregation" be an appropriate term?

Except that Google, Microsoft, Facebook and Amazon have been at the table when GDPR was written and will be compliant with it. So it's a completely bogus argument.

What would most likely happen is that companies that act as "middle men" would pop up that provide the functionality those sites do. But TBH i doubt that would ever happen in the first place, even with much stricter rules. There are way too big of an audience to be lost.
