As far as I can tell, that still makes it harder to get into the UK than many other countries in the EU.
Easiest way into the UK is probably to naturalize in some other EU country first. I wonder where is easiest? Germany, Belgium, Ireland?
It's unlikely that Germany would be one of the easiest, as it requires 8 years of permanent residence to become a citizen. After living in Germany for 8 years it's unlikely you'd still want to move to the UK anyway, as you would have learnt the language and have come to appreciate the higher quality of living.
The question is entirely academic for me, since I'm close to having a green card in the US. But is the quality of life in Germany really better than UK? I'm from South Africa and speak some Afrikaans, so I suspect I could learn German more easily than your average English speaker.
Of course one disadvantage of Germany is they don't allow dual citizenship...
Better act fast though, before the UK "brexits" the EU. I have no idea how difficult it would be for people(/me) to keep their(/my) address and company in the UK in that scenario.
But it's doable...
