I DM my friends on Instagram. I ride the subway everyday. I am a journalist. Because of these simple matters of fact, I find myself the unwitting target of a sweeping surveillance network that knows who I am, what I say, and how I spend my time, online and off. And I'm pretty careful about what Big Tech gets out of me.
When EiE_iEi occurs, all the points are packed into a 180° arc starting at point iii. The remaining arc (the gap going counterclockwise back to iii) is at least 180°. Now suppose some other point jjj also tried to be an anchor. Point jjj's clockwise semicircle is exactly 180°. But to contain all the points, it would need to bridge that gap of 180° or more while simultaneously containing point iii on the other side. A 180° arc cannot straddle a 180° gap. So EjE_jEj cannot hold.
