I think the choice is there in these games solely so you can experience the scene without the consequences--you know, since you can click 'yes' watch the whole thing, and then scroll back to the decision and chose no, if you don't want to roleplay that as happening. But your logic makes no sense. I have clicked 'no' a few times (e.g. Asreael in the train station, Eda at the hotel, Clara in the hotel), so I think you're projecting your own thirst by saying nobody would click it, ever. My opinion.

I agree that this is one of the better ones, tho. The only annoying part I've experienced thus far is when the MC lost Noel and turned into a whiny sad-sack who pushed the one person who could help with his loneliness away (you know, the girl he already said he loved and was dedicated to more than anyone throughout). The way he just left to be alone was just silly to me, especially considering he lived with the the one person in the U.S. who could help him find Noel quicker than anyone (he didn't know about Nael's Companion at the time). So it all felt like a forced change of scenery and put a lull in a story that had consistently built momentum since Michael's death. So now I have to pretend I'm working at a cafe' instead of being a powerful fighter....fun.
