You have a funny vision of what "complicated" means. Needing only your everyday national ID for travelling (without the need for visas, passport or permits) and saying "hello" to an officer is not something difficult for many people.
UK/Schengen and Schengen/Schengen are so close compared to EU/Rest of the world, that the differences are imperceptible.

But they are so much perceptible, when you live inside Shengen. Nobody says it is complicated (as an absolute) to go to the UK. But it is more complicated (as a comparison) than travelling within the EU. I don't even understand how that can even be in question.
See, when I'm traveling from Berlin to Poland I have no delay. I only notice the border because speed limits are now different. I do that on a regular basis. Last time I traveled to the UK I actually had to wait in line to show my ID. It's less of a hassle than crossing the border between Botswana and Namibia, but more than between Ger/PL. It does take noticeable time. There are people commuting across the border in many regions of europe and for them, 10 minutes every morning do add up.
